Most people don’t worry about it for the same reason they don’t worry about GitHub abusing their GitHub account and are even willing to use “login with GitHub” to access their other accounts. Account takeover by a third party is a bigger risk. If you’re concerned about supply chain risks, there are more important concerns than “what if GitHub itself is a bad actor.”

It’s solvable if you’re willing to self-host your PDS.

But I’m skeptical of the attempts to make a PDS an “everything account.” Why should you use the same PDS for your social media posts and your git repos and your blog posts? Seems like we need to get better at locking things down in practice before that kind of centralization?

  > Most people don’t worry about it for the same reason they don’t worry about GitHub abusing their GitHub account

  Even with GitHub we don’t hand over our private keys to the GitHub server, though.

  When I commit to my repos the commits are still signed by the private key that lives on my computer. Someone could take over my GitHub account and they wouldn’t be able to sign commits with the private key on my PC.

  They could technically add a new public key and sign new commits with that key, but I could cryptographically point to the change and show that the key changed at time of takeover and disavow it.

    Good point, but how many projects require people to sign their git commits? it's not something I've had to do at all.

    If you're not signing them then hosting on GitHub gives GitHub the ability to do arbitrary commits in your name. The repo's HEAD is whatever GitHub says it is.

    Atproto gives users choice for where their data is hosted as well as the ability to migrate their data to a new host. Users who dont want to put trust in a provider can host it themselves. How is that not an improvement over being locked in to a single centralized provider?

  • skybrian

    today at 4:55 PM

    If you assume that Bluesky won't suddenly turn hostile (we'll get some warning) then being able to migrate your PDS is better than what X gives you and about the same as being able to move your git repo off of GitHub.

  This "social coding" thing Tangled has going on is cool but I don't want it. I hear they're figuring out private repos but for me, I don't want the same account I use for social for my code.

  I'm probably in the minority though.

  • OneDeuxTriSeiGo

    today at 5:25 PM

    Note that you don't have to have a social account. And there's work on the semi-distant horizon for creating sub-accounts which are independent but all under a common top level account kinda like how GPG conceptualizes subkeys or cryptocurrencies handle derivation keys.

    For the current moment though you can just create an atproto account without creating a bluesky account. Tangled for example supports this on their site by creating one for their PDS and you can always move to another PDS in the future.

    The over-arching idea isn't that your code is tied to your socials but rather that you can have a bunch of disparate services that you can interlink over a common identity layer and that those services are only loosely tied to the people/orgs hosting them but could be trivially hosted by anyone else.

  I do. I registered it directly with my ccTLD’s registry, which is a government agency. It’s tied to my national ID number, or to my company’s tax ID.

  If my DNS provider messes up, I revoke their DNSSEC keys and point my domain to a different provider.

  This cheap criticism of the headline doesn’t actually apply to the problems brought up in the article:

  > Your PDS operator can post as you, like things as you, follow people as you, and it would be cryptographically indistinguishable from your real activity. The signatures are valid.

  Your domain name owner or DNS provider cannot redirect your domain name to a different server and cryptographically impersonate you.

  • jacobgold

    today at 3:51 PM

    Your DNS provider can obtain a TLS certificate for your domain and cryptographically impersonate https://yourdomain.tld

    It's not exactly the same thing but it's close.

    • Aurornis

      today at 4:00 PM

      Still not the same thing as in the article. Server side TLS certificates are widely understood to be tied to the current owner of the domain.

      In a social protocol or context, I would expect a private key to be in the private control of the individual, such as when someone uses their private key to sign an email or git commit.

      The purpose of signing your emails or commits is to provide a good indicator that it actually came from you, not someone who managed to get access to your email account at the time.

        > The purpose of signing your emails or commits is to provide a good indicator that it actually came from you, not someone who managed to get access to your email account at the time.

        This is true and it's still true in the ATProto ecosystem but in a different context.

        It asserts that events and records are authored by your PDS, not by you specifically. Which is certainly closer to the intent of TLS certs.

        And technically you can maintain a PDS proxy that can only host, broadcast events, and receive content but that doesn't have any keys or signing capabilities.

        Then you can have a local PDS that does your signing and sends signed events and records (basically signed state updates) to the PDS proxy to actually emit to the network. This then allows you to lock your keys behind a hardware key to better lock everything down. Of course there are trade offs to this. If it requires physical auth then it can only work on one device at a time or you have to self host it homelab style at which point it might just make more sense to host the PDS yourself anyways.

        There's a project thats working on this very thing but I've not kept up with it and I can't remember what the name of it is. If any ATproto people in the comments knows the name/link feel free to reply under this to enlighten me + everyone else.

      • arjie

        today at 4:59 PM

        If you use your private key to sign your commit, I don’t see how your PDS can impersonate it. There are different layers here. Your commit is still signed by you and non-impersonatable by the PDS operator. But the ATProto layer signing is under control of the PDS. So in that case you’d see either unsigned or differently signed git commits being reported at the ATProto layer as by you.

        That seems entirely normal. The PDS handles ATProto actions but it cannot modify the git signature (obviously!). It’s no different than the fact that GitHub can post that you’ve committed a “verified” badge commit by adding a new signing key to your account and signing new commits with it.

        The storage entity can always claim power over this by reporting a new key and signatures with that key. Seems entirely normal.

      • jacobgold

        today at 4:07 PM

        This is why your DNS hosting provider, despite not being the "current owner of the domain", being able to impersonate your site (terminate a cryptographically secure TLS session) with your customers is a similar problem.

        I do agree they're not the same but the trust and risk are very similar.

        • edoceo

          today at 5:14 PM

          DNS providers and registrars seem to have a longer trust established, that reduces the risk.

          They are similar in that: jerks can be jerks. But one of the jerks I've trusted for 30 years and I hardly know the the other jerk.

  • OneDeuxTriSeiGo

    today at 5:30 PM

    Kind of. Your PDS can impersonate you but you can have higher ranked "recovery keys" that can undo/recover all the damage.

    Socially whether you can explain off that your PDS acted maliciously or that it was hacked or whatever is a different story but if you keep recovery keys for your DID you can take back control and undo everything your PDS did that you didn't authorise pretty trivially. The UX for it needs to be improved but technically the process is super simple/straight forward.

    And those recovery keys provide a mechanism for declaring "hey i didn't do this I was hacked" on top of specific events but nothing for taking advantage of that cryptographic opportunity has been built out yet.

    Right, if Bluesky ever does do something hinky with your PDS, the operation will be signed with their key and persisted in the operation log which they're unable to touch.

  Yes you do own your domain, as much as you can own your house. Your hosting provider can only take down your hosting, not your domain. Seizing domain names isn't very common. And by the way, with Web3 domains, you have full ownership via your own private key, with no need to pay rent. Is it possible to lose your house that you own? Yes. It's far more rare to lose a domain you own, by it being seized.

  DNSSec is used to prevent unauthorized stealing of domains. Furthermore, if someone does steal one domain you own, they don't steal all your accounts across all domains. If they take over your hosting, that's a fixable problem -- you just repoint the domain.

  Now, having said that, I designed the Safebox exactly to prevent these scenarios from happening, and create an actually solid foundation for decentralized social networking, AI workloads, etc. If anyone is interested, probably the best link to begin reading about it is: https://safebots.ai/about (If you do, I'd love to hear your thoughts)

    • EGreg

      today at 4:43 PM

      Right, but neither do these problems apply to domains, as much as they apply to ATProto accounts.

      You don't even have the frameworks that are available to protect domains. (Domain lock, transfer, etc.) And registrars are regulated by laws and frameworks in ways ATProto hosts aren't. Don't get me wrong, if a registrar transfers your domain due to a social engineering attack on the registrar, then you might lose it (an attacker almost did this to me once via a SIM swap, and I had to call GoDaddy to prevent the transfers). But that's not the same as, say, hacking the web hosting server.

      In any case, tptacek, Safebox is supposed to solve these actual problems, by making sure no one can actually get into the box (no ssh, etc) so it's a "neutral ground" that no one can really "own", "redirect", steal keys or impersonate you. If you read https://safebots.ai/about you'll see what I'm talking about. If you do, I'd love to read any feedback you might have, given your background in security!

  • ranger_danger

    today at 4:00 PM

    Seizing domains is a lot more common than it used to be though, enough that it's a real concern for me personally, and I'm not sure there is a viable solution at the moment. There is also the concern of countries/governments or specific ISPs simply blocking access to one's domain in various ways... and the number of authoritarian regimes that have been blocking large portions of the Internet has only grown with time.

    And regarding DNSSEC... if your domain is taken by the registrar (court order, ToS violation, etc.) or a government that can command the parent TLD to act, they can just revoke your old key and transfer the domain to someone else (or setup a placeholder under their own DNS) and now your protection and all concept of ownership is completely gone without your consent. This happened a few years ago with Epik seizing the soyjakparty and kiwifarms domains, including their hosting from a subsidiary company Terrahost... and KF has never even lost a lawsuit, but there are some specific people that really don't like them, and have gotten adept at claiming ToS violations via every possible company that touches them in order to try to make them go away.

    I can legally shoot and kill intruders due to castle doctrine and stand your ground laws in my physical home. And legal invasions require being in front of a judge and a search warrant.

    A domain can be seized for 'terms of service' (aka kangaroo court) reasons. Stand your ground nor castle doctrine doesn't apply to your digital house.

    • iamnothere

      today at 4:34 PM

      Domains typically can’t be seized for arbitrary ToS violations, as registrars who do this can lose their accreditation with ICANN (and thus their ability to host domains at all). If the registrar could “frame” you for something like DNS abuse then maybe they could justify a suspension, and if they don’t unsuspend it after you correct the issue, you’d have to file a complaint with ICANN to (hopefully) get it back. If something like this happened and became public, though, the registrar would lose tons of business, as people would develop doubts about the registrar’s reputation.

      Let's compare apples to apples, shall we.

      How many houses were actually seized, repossessed, commandeered with "eminent domain", slowly taken over via "adverse possession", encroached on with easements and air rights, and whatever else? Versus how many domains?

      There is no violence on the internet. You can't shoot intruders. And that's a great thing.

      Put in legal terms, you do NOT have this level of ownership to your house... and you certainly do not have sovereign immunity on your land: https://en.wikipedia.org/wiki/Allodial_title

      You probably have something more like this: https://en.wikipedia.org/wiki/Freehold_(law)

        I'm not sure where you're from, but in my state, we have "Castle Doctrine" and "Stand your Ground" laws.

        That means if you are a home invader, I can legally shoot and kill you. There'll be an investigation, but both statutes are affirmative defenses to killing.

        Its not that I want to, or look forward to it. I don't, and I hope I never have to. But I will, if I'm forced.

One of the core features of AT is the ability to move your repo hosting provider (PDS) at any time. This is the "data portability" problem that ActivityPub never solved.

Bluesky Social, PBC runs a PDS service (bsky.social) for free, there are a number of free public alternatives, and thousands of users self-host.

  You have the ability to move, as long as Bluesky Social PBC allows it.

  They hold the keys for your DID. If they don't allow you to move to another PDS, you can't move. The original theory was that you'd hold the private keys, but that's something that would hugely limit adoption so they decided to hold the keys themselves.

  In terms of moving your backlog of posts to a new server, part of the issue is liability (not merely legal liability, but reputational as well). When you have a user on your platform and they're posting stuff, you're moderating them in real time. If they turn out to be a horrible troll, you've get the reports. Let's say a horrible troll has been on EvilServer and EvilServer has been ignoring the reports against them. They now want to move to your GoodServer and bring all their post history with them. As an admin of GoodServer, you can't see that everyone has been reporting this troll for years. They're now moving over lots of horrible, inflammatory, potentially illegal posts to your server.

  • quasigod

    You can register a recovery key which allows overriding the signing key. This allows users to move from an adversarial PDS. I do think Bluesky should push for more users to add a recovery key, but I also understand why they haven't.

    Moderation tools arent limited to specific PDS's, labels are public. If an account has received many reports it will have been labelled by Bluesky's moderation account and other independent labellers. A PDS can check against these before allowing an account to migrate if they choose to. I'm not sure any are currently doing this, but this is something that can absolutely be improved in current implementations, not an inherent limitation of the architecture.

I think most people don’t need to worry about their host abusing its power to impersonate them, but the cool thing is, the people who do need to/want to worry (journalists, politicians, celebrities, activists, open source maintainers, etc etc etc) can self host a PDS and be a lot safer, and still interact with everyone else.

Sure, somebody else holds your identity, but it's pretty easy to control it yourself. By its nature if you're using somebody to host your stuff, you're trusting them with it. I made Cirrus so you can self-host your PDS for free, but you still need to trust Cloudflare to run it.

Is author new at the whole web thing? Yes, people trust remote web servers. Yes, if you link multiple apps to an identity server (be it atproto, google, or self-hosted OpenID server), and your identity server is compromised, attacker will be able to impersonate you or lock you out.

This is just how the web works, and there is no easy around it without losing features people care about. Sure, you can do client-side encryption and pretend serve can't see the plaintext, but it's just a theatre, see Hushmail incident for example.

And having people export uber-key by default is pretty terrible idea. Sure, allow advanced users (like post author) to do it. But for the common person, the exported key is just another way to get account compromised, via malware or backup provider hacking. Or if they are not backing up stuff, then the key will get lost next time they upgrade.

    Some services only allow signups from the big free providers like gmail/outlook/etc. because those providers are doing more consistent KYC and anti-spam measures than anyone else by far, and unfortunately it does cut down on the amount of spam by a lot. For most people nowadays you cannot even create a new gmail account without directly linking it to a mobile phone.

So does a CA issuing my certificate, but there is some oversight in what they do.

• jeroenhd

  That's different. While your CA can hand out new certificates, it doesn't know your keys (unless you messed up when uploading your CSRs).

  CAs have to prove they're not faking certs through the certificate transparency logs, there's no such limitation on Bluesky.

  A more apt comparison is a shared host that does certificate management for you. Those are also often considered less secure, of course.

        UFO sightings stayed confined to the 1950s and were a reaction to new technology?

        Or were the UFO sightings in the 1950s the only UFO sightings that were a reaction to new technology?

        I'm not sure how this being clarified will be able to explain how identifying the writer of text is the same as a UFO sighting in 1950, but I'm open to it, I try to stay rigorously rational (c.f. X does not imply Y in first pull quote)

            FWIW it did used to be true that the 3rd party services were junk. And I don't support the idea of humans just winging it when there's consequences.

              > This is false, it is trivial to find humans with 99%+ accuracy

              Sorry but no, this is also false. AI is largely trained on human data. What it outputs is also largely what a human would output. We could both easily make up the exact same sentences and there is NO way to tell what the real source of a sentence is, especially considering the source can be multiple things (AI and human) at the same time!

              There is no amount of literature you could provide or anything you can do or say that would change my mind on this.

Wait what?! For a protocol that incorporates the DID spec this is disappointing to discover. Unless I'm mistaken the DID spec allows provable hierarchical relationships between DID identities – why can't a child DID be created from our master signing identity that has the authority to CRUD on our behalf but still be provably distinct from our root identity?

Not even sure why the PDS would require our signing key that just seems very sloppy to me. As you can tell I know very little about atProto, and I did participate in the development of the DID standard and I am dismayed to see such an inelegant solution in such a promising protocol.

  Oops upon closer reading of the article and the comments here i see that the atproto standard does apparently allow for the above, at least to some degree. If there is indeed hierarchical support for the DIDs then you should be able to disavow any child identity from a master identity and leave no public uncertainty (ie the true owner of the key hereby disavows the following sub keys)

  So if the worst case scenario presented in this article took place where a PDS was falsifying information and pretending to be you, you could presumably somehow revoke the child key that you provided to the PDS. I'll have to look more closely at this

  You could even publish a signed selective retraction (delete the fake posts or mark them as fake) with proof that you control the key 1 level above the key that posted them

Both nostr and atp sucks at key management imo. The Farcaster network does a good job here with their chain of trust model and a smart contract on etherium blockchain to recover identities in case of losing access to a private key. Ironically its also the blockchain aspect of Farcaster for which I never tried it.

Why aren't the keys stored encrypted?

It seems most ppl who dislike X has already settled, a small amount moved to DeSo like atp or ap, most just stayed or went offline. Unless China GFW magically collapsed, there seems no reason ATProto user base will continue to grow. So, when will the monetization/enshitification phase begin?

I'm asking this not bc I like enshitification, but the app view design seems such a perfect fit for user data mining/targeting, that it's hard to believe it was not part of design consideration in day one.

Centralization is always a trap.

No idea why people have such a hard time joining and supporting the Fediverse.

  How is the fediverse different. Can't the owner of an instance post as you? Can they read all your data stored on their instance and pass it to anyone they want to?

• webdevladder

  today at 2:55 PM

  Higher friction and fragmentation are Fediverse features (not bugs) that give it a different grain. ATProto has different tradeoffs that lead to a different form of social media. I'm glad both exist, and bridging efforts are worth paying attention to for anyone frustrated with the distinctions.

• today at 3:46 PM

What's the evidence for this? I'd be very keen to understand. This looks Claude written which is fine but adds an extra layer of skepticism for me.

Probably doesn't matter for the "40M+ users", most of them have churned at this point and growth is negative. This is good critique for the next iteration of open social protocols, but fundamentally atproto did not fail because of technical reasons. The next iteration should make privacy the default and core to protocol, and be very mindful of how the leadership / social dynamics played out.

        Arguing that success is purely about the ultra high numbers seems to miss the forest for the trees. Is HN a failure because it did not reach the level of DAU as Reddit? The quality of discussion and community here is certainly substantially higher. I feel the same about Mastodon and Bsky vs Twitter. I’ll take community I actually want to engage with over sheer numbers any day.

    They had a vision and goal to change social media, to get people away from Big Social. They haven't failed in the technical sense of closing, there are less than 1.5M daily (the stats trackers are starting to shut down), but they will also never fulfill on the promises. In the startup world, this is called a zombie company.

    One way they failed hard is that they talked about how they were against the investors and VC incentives, then they took $100M from Bain Capital (PE) just after peak user count, but didn't tell us for almost a year. They could have put up a simple $5/month to support the cause, but they took investor money instead. This is why I left.

  Bluesky / AT is the most successful open social network in history and the only one to become culturally significant. It has been adopted by presidents, celebrities, journalists, and mainstream users.

  Bluesky has ~50M registered users and has sustained ~5M monthly active users for long while. There's no reason to believe it will fall substantially below this level.

  It is also in the process of adding (decentralized) subcommunities, which I expect to be really cool and have a large impact on growth.

  • tptacek

    today at 4:01 PM

    "Registered users" is a meaningless statistic. Daily active users has consistently declined.

    • jacobgold

      today at 4:12 PM

      I'd be the last person to downplay the fact that the Bluesky app has a serious retention problem. But it has "broken through" in an incredible way and DAUs/MAUs are quite stable.

      Registered users is not at all meaningless. Bluesky has those user's email addresses, the mobile app is still installed on many of their devices, they have accounts, and they can potentially be reactivated.

      For example, if Bluesky announced a feature exciting enough, like subcommunities, it could email those 50M users and possibly bootstrap a serious open network competitor to Reddit.

          Based on your comments, it seems like you're trying to spread FUD?

          The stats page you linked to explains exactly what's going on. These spam PLC identities have nothing to do with with the tens of millions of real Bluesky registered users.

          Either you misunderstood or you're being intentionally dishonest.

              You still seem to be implying the number of real registered users on Bluesky isn't ~50M, which it is. The PLC identity spam you referenced is not being counted in this number.

                It is confusing to say "users" when it is actually "accounts", humans tend to associate "user" with another human, where as "account" can cover people and bots (many on atproto)

                eg. I personally had more than a dozen accounts

                  today at 5:28 PM

                  That's a fair distinction to make but my (educated) guess is that something like 95% of users have a single account on Bluesky.

                  Most users signed up by downloading the app or visiting the web site and created a single account.

                  As a point of reference, the official Google Play store independently verifies that the Bluesky app has had 10M+ installs.

                  https://play.google.com/store/apps/details?id=xyz.blueskyweb...

                  There are no official stats on the iOS app or web but those are both likely similar or larger sources of users.

                    today at 5:58 PM

                    I would counterpoint that a non-insignificant number of the accounts are spam/bots. Jaz's stats overestimate because it does not remove certain accounts which have been takedown/deleted, let alone those that remain. I have shared analysis of this on HN, Bluesky, and Discord to avoid making educated guesses.

                    The reality is that a significant chunk (>50%) was Blue MAGA, or turned off by them, and I see little prospect that they will reactivate. Outside of the Bluesky echo chamber, there is a deep brand association with Bluesky being primarily political refugees. They see Bluesky as the left-wing Truth Social. I've asked hundreds of people IRL if they have heard of Bluesky, they are far more likely to have this brand association than to have heard of "atproto" (more than half vs 1-2% / can count on one hand).

      • tptacek

          today at 4:39 PM

          Of course investors care about registered users, for the same reason I explained. But yeah, they do care a lot more about retention and growth rate for good reason. Bluesky Social, PBC has raised $120M+ dollars from investors.

This is where non-financial use of blockchain could really shine, IMO. Self-sovereign identity management with a smart contract-based process for recovering ids if keys get lost or hacked. Blockchains are pretty out of favor these days, but I really don't see a better solution for decentralized identity management.

  > smart contract-based process for recovering ids if keys get lost or hacked

  How would that even work?

  • tarpitt

    today at 4:42 PM

    Perhaps some sort of namecoin or ENS-like petname system with multisig or some type of scripting that enables different recovery methods.

    For example, you could set your petname up so it can be controlled by a single keypair, which can be overridden after a certain time by a ring signature based on keypairs held by friends, family, peers, and trusted computing devices you leave in a safe deposit box.

    Or maybe you could trust your identity with some centralized entity, but only as part of a 2-of-3 multisig with yourself and another trusted entity.

    Basicially namecoin with bitcoin-like scripting controls.

  • TheDong

    today at 3:13 PM

    If someone's account gets lost or hacked, the person with the most incentive to own that account is usually the original owner, so just give it to whoever is willing to pay the most, problem solved. We can call it "proof of stake", where you always stake a certain amount to keep owning your account, and when contested, whoever stakes the most gets it.

    Poor people don't deserve rights on the blockchain anyway, it's not like they can afford the transaction fees, if they didn't want their account stolen they should have tried being rich, or buying into nearer the top of the pyramid.

    Don't worry about people who pass away or lose internet for an extended period, we'll deal with that in v2, when we get "proof of death" and "proof of internet disconnectivity" on the blockchain somehow.

    /s if it's necessary

    • tarpitt

      today at 4:52 PM

      I think you're right that transaction fees are a key problem. It's ultimately a bandwidth problem. You're bidding for the limited vbytes, and the bidding price only increases with traffic, kicking poor users out.

      I think the key thing to recognise with petname systems is that there doesn't need to be this sort of "top-level consensus" as opposed to ecash systems.

      You can have two instances of namecoin, say Namecoin1 or Namecoin2. You can just have different domains like alice.nmc1 and bob.nmc2 and have them interoperate properly. You can just keep forking blockchain-based petname systems to overcome the bandwidth/fee problem.

      What this means is that Namecoin1 full nodes don't need to synchronize all the domain names on Namecoin2 and vice-versa. Similar to TLDs on DNS. We can imagine that there might be different petname TLDs for different global regions, and they might be merge-mined.

      This isn't true for money applications like bitcoin or eth, because by forking BTC or ETH or something, you are creating new coins.

  What is the incentive for an individual to participate in a non-financial blockchain?

  Bitcoin-style blockchains “work” because everyone gets the possibility of a little reward for all the hassle and non-negligible CPU time of being a node.

  • tarpitt

    today at 5:04 PM

    Good question, this made me think.

    You get a reward for being a mining node, not just any node. Even then, do miners have much incentive to share blocks, other than the ones they mine?

    I think the incentive is mutual for most nodes (aside from the mining aspect). People will set up a node to accept transactions in an automated manner, or to have higher confidence in the state of their accounts.

    It's like being on the floor of the stock market. People participating want to be where all the information is (for their own benefit), and there is incentive to bring others in and share information (because it increases the amount of information you have).

    I suppose you could be a "selfish" node. The bitcoin-equivalent of someone who leeches and never seeds. But the advantage is low relative to the amount of money moving around. Most people don't care about the bandwidth of running a bitcoin node, they care about latency. Unlike bittorrent, there isn't a de-facto finished version of the file being synced: it's a constantly-updating list that everyone wants to have the latest version of. I can't find the words, but this seems to be the fundamental difference.

    What's the incentive for people to participate in file sharing networks? To some degree it's access to a world of free media (same as access to a world of decentralized identities), but to a large degree it's an interesting hobby/excuse to be interested in tech. Some people have racks of hard drives dedicated to hobbies like this, just because it's interesting and is worthy.

  • majorchord

    today at 4:18 PM

    For me the incentive is being able to own an identity that nobody can take away from me. And the assumption is that services will support this type of identity, so I don't have to make accounts on other systems that people can take away and now I've lost all access to any data I had.
