Warning: You cannot delete posts or comments on Lemmy. It stays up forever, and is in direct violation of GDPR and other national privacy laws.

Title says it. Apparently lemmy devs are not concerned with such worldly matters as privacy, or respecting international privacy laws.

  • It gets worse: everything you post to Lemmy is sent to multiple other servers automatically. Those servers may be in jurisdictions that have very different privacy laws than the server you post from, or that hosts the community you're posting to. You have no legal agreement with those servers.

    We're not done though. The ActivityPub standard makes delete optional, and other servers could be running anything, not just Lemmy. Some of them are probably running somebody's janky pet project that implements half of ActivityPub, poorly, on a jailbroken smart light bulb or something.

    Lemmy should implement proper post deletion, possibly with a delay to allow moderators and admins to inspect deleted posts, but expect anything you share via ActivityPub to follow the once on the internet, always on the internet rule even more than in the past.

    • Delete buttons are just a placebo on the Internet anway. At least activitypub is honest about that.

    • Almost like the entire platform is based on the idea that one server/owner can't be in charge of the data.

      Don't get me wrong, not picking a fight, just what op said is kind of obvious to me. You're picking a social media that is democratized and is federated with everyone. The natural tradeoff is that your data is not housed on one server... Which obviously means it's not private.

      Idk, the fediverse is a great place, but I would never post anything here I ever wanted to be private. It's not an accident, it's literally by design.

    • Lemmy should implement proper post deletion, possibly with a delay to allow moderators and admins to inspect deleted posts, but expect anything you share via ActivityPub to follow the once on the internet, always on the internet rule even more than in the past.

      How would this be done? Like you mentioned, anyone can run a modified instance of Lemmy that does not honor delete requests. I suppose you could put something that retrieves content from other servers as a pull operation instead of a push, but that's going to break Lemmy's ability to work with other ActivityPub applications (at the very least).

  • OP is simply incorrect.

    I'm coding a Lemmy alternative right now and have been testing this functionality out extensively. Deletes of posts and comments certainly federate, I've seen the AP traffic to make it happen. Also, the docs: https://join-lemmy.org/docs/contributors/05-federation.html#delete-post-or-comment

    I haven't tested what happens when the 'delete account' button is clicked... Mastodon solves this by sending a 'delete this user' Activity to every fediverse instance so there's nothing about ActivityPub that makes removing an account and all it's posts in one go impossible.

    • Deletion of entities is optional in ActivityPub. That, by definition, makes known-removal of an account and all its posts in one go impossible, because a server can just ignore the deletion activity.

      • Yes, although the server will not ignore the deletion activity if that server is running Lemmy. We're talking about Lemmy here, not the fediverse as a whole. OP singled out Lemmy in the post title and said "lemmy devs are not concerned with..."

        I'm sure there is more to be done in this area. It'd be great to know for sure which software treats deletion activities properly (I'm really unsure about Kbin, I think it does not) and which does not so instance admins can make informed decisions about who they federate with. Perhaps this information could be made available right within the UI that Lemmy admins use to control their instance, rather than an obscure documentation page somewhere...

        IMO having deletes federate should be part of a minimum standard all fediverse software has to meet (plus mod tools, spam control, csam filters, etc) before it is allowed to federate but obviously we're nowhere near having that sort of social organisation.

  • seems weird this expectation of privacy on public sites built for public consumption of public content posted by people publicly.

    i mean, i get wanting to control your data. the software i use allows for this ( the 'bins offer a user-level purge).

    but privacy? seems weird

  • This is definitely a con of Lemmy for me. I like to be more privacy focused but Lemmy gives you 0 privacy on whatever you do on the website. Anyone who wants more privacy on Lemmy is told you have no right to privacy, don't expect any privacy, everything you do is public on the internet, etc. A massive boner killer for me. I think basic things like deleting your own post or comments should actually get removed from all servers, PMs should not be viewable by anyone except the recipients, and what you vote on or subscribe to should be private. Lemmy doesn't sell your data but that's because anyone can take the data for free. I thought this stuff was because Lemmy is still new and will get to it eventually but the push back seems to say this was a choice or is not broken. I ended up exploring different social media alternatives but I like the style of Lemmy better since it is more reddit-like with an active user base plus has different android clients. I don't like kbin because it shows who upvoted or downvoted something to everyone - it's not accountability when it erodes your privacy.

    I used to comment on Lemmy more but then I ran into this problem when juggling multiple accounts, Liftoff sucks ass at letting you know which account you are logged into (I use Summit now and it is better at it) so I ended up getting my accounts' wires crossed when I thought using the drop down on your accounts changed your account but no you have to go to manage instances to switch which was not intuitive. I ended up abandoning the accounts when I couldn't figure out how to actually delete the post from the server.

    Edit: man I wish I saw this sooner, might be time for me to either stop posting again or look somewhere else.

    • While I didn't find any factual issues in a quick skim of that article, I really don't agree with its tone.

      The Fediverse is radically public. That's the nature of a protocol like ActivityPub, not a bug to be fixed. Using it for anything you're not comfortable with being public forever is a mistake.

  • Effect of ActivityPub, not Lemmy. All federating systems function similarly, because it's a feature of the protocol.
    If instances want, they can ignore delete requests and your content stays in their cache forever (remember Pleroma nazis from couple of years ago?) - now, that is an instance problem that might be a GDPR issue, but good luck reporting it to anyone who cares. At best you can block and defederate, but that doesn't mean your posts are removed.

    The fediverse has no privacy, it's "public Internet". Probably a good idea to treat it as such.

  • GDPR is international now? Do I need to break out Nelson Muntz when some Euro type thinks European law is extraterritorial?

    Don't make me break out Nelson Muntz, please.

    • It's mostly important for when you wanna do business in the European markets.

      The alternative is to be blocked by most of Europe entirely. Happens usually to tabloid news sites as they are often in violation of anti misinformation and hate speech laws. It's also why they could sue Facebook so easily as otherwise Facebook would be non-GDRP compliant and be blocked there.

      Lemmy however isn't exactly for profit, so sees much less scrutiny. This is primarily for business after all. Lemmy doesn't have ads, doesn't take users money, nor does it sell products. It also does not actively distribute illegal media either.

      (it should be noted that it's usually not the EU doing the blocking but rather so websites choosing to block viewership from the EU because they'd rather do that than get sued to hell)

      • "Lemmy" doesn't do ANYTHING. Lemmy is server software. It has no agency whatsoever.

        Individual Lemmy sites might be beholden to the GDPR (or not, if individually run). But any site hosted outside of the EU can wave its ass in the faces of EU officials trying to enforce the GDPR.

  • Mods and admins can remove posts and they don't stay on the server. If you delete it yourself, then it stays. Comments stay deleted, though and is replaced with a 'deleted by creator' message.

  • You know, I think I'm going to make some software that just siphons every ActivityPub message (ignoring delete requests except to log them) and call it "GDPR THIS". The amount of mysticism and confusion around two very basic concepts (ActivityPub works by copying profusely, and the GDPR has no weight outside of the EU) just leaves me baffled here.

  • Message your admin and ask for purging of that post/comment/user.

    • Then message every federated server's admin.

      Then message every federated server's federated servers' amins.

      Then ...

      The number of surprised Pikachu faces people are displaying here is actually pretty funny now.

      • Technically, yes. If the law is of concern, if you're an admin, purging it from your database will be the only extend your power can reach. If privacy is of concern, while purging will not federate, delete/edit will, so edit all comment into gibberish before deleting your own account, and then ask for it to be purged. If that's unacceptable then best not use social media at all.

  • That's a pretty uncharitable interpretation, especially considering Lemmy is developed in and funded in part by the EU, and the "staying online forever" thing is a consequence of Federation (and one they're working on remedying).

    If you were worried about this sort of thing, perhaps you should have done your research about the platform before making an account so you could bitch about it here. You definitely don't sound like the voice of reason when you couldn't be arsed to figure this out before you made an account.

    • So you can't make an account on this platform if you don't agree with how it operates? By that logic no criticism of the platform by its users is possible, which is a great way to ensure it never gets better.

      Edit: Let me make this clearer:

      Saying in effect "yet you participate in lemmy" to dismiss the OP's concerns is ridiculous. If this logic were taken to its endpoint, there would be no valid criticism of anything lemmy ever did.

      Maybe that's your goal, but I would rather not blindly defend lemmy because I like it. I'd rather make it better, and that starts with criticism.

      • I mean, yes?

        If you do not agree to the terms of a service, do not use the service. This is the case for essentially every system ever. You can go complain about it on Reddit or something if you like.

      • It took this person 20 days to post this. They didn't create their account to post it the same day or even the next day, ergo, they figured it out after the fact.

        If they really had an issue with stuff like this, why pray-tel weren't they already doing their due diligence to ensure that the service they were signing up for didn't violate the GDPR in ways they didn't like? That seems like a gross oversight by someone clearly incensed by it.

        (Also, it continues to be questionable whether it's actually breaking GDPR rules, and even in that regard, it would be individual server admins responsible for enforcing GDPR compliance.)

      • I don’t agree with that reasoning. It’s entirely possible for someone to be personally accepting of the Fediverse’s privacy issues, but make an intelligent, well informed, coherent critique of them.

  • Well it is pretty much impossible to delete anything on any federated service. It is technically just not possible without opening a whole other world of problems.

    I always like to think of the fediverse in some way like emails. If you send an email, the moment it leaves your mail providers server it is pretty much impossible to stop.

    Basically think before you post. The internet never forgets, the fediverse especially so.
