If at some point you want to delete your account and have your posts and comments be gone, you better delete it all manually before you actually delete the account, because that deletion process does not really work as advertised.

For my main account on world (which runs an outdated lemmy version), it seemed like at least the account deletion was federated so that my user page was no longer browsable from other instances, but none of my posts, comments or images had been deleted, not even on the home instance.

The homie @MrKaplan@lemmy.world helped me by manually deleting my stuff, but it seems like that has only worked for the home instance, posts and comments seem to still be readable from other instances (except for some of the images that MrKaplan manually deleted too, but that was only possible up to a date not too far in the past because lemmy used to not associate user uploads with the accounts). So my old posts from the world account can be viewed just fine from other instances:

For other instances that are more up to date the process is even worse imo, while locally things seem to get deleted, federation does not seem to happen at all. For example you can still browse my deleted slrpnk or lemmee accounts from other instances just fine:

https://slrpnk.net/u/achtungdrempels@lemm.ee

https://lemm.ee/u/AchtungDrempels@slrpnk.net

Account deletion in piefed works kinda like the old lemmy system (as on lemmy.world), and nothing gets deleted except the user page (which also seems to get federated), the posts and comments stay up.

Thought this would be interesting to some, if i had known what a mess this would be (obviously expected some federation issues, just not like that), i would have manually deleted everything. I deleted all these accounts in December, maybe this has been addressed somehow in the meantime, personally i'd have trust issues in this process.

Over the past 5-6 months, I've been noticing a lot of new accounts spinning up that look like this format:

• https://instance.xyz/u/gmbpjtmt
• https://instance.xyz/u/tjrwwiif
• https://instance.xyz/u/xzowaikv

What are they doing?

They're boosting and/or downvoting mostly, if not exclusively, US news and politics posts/comments to fit their agenda.

Edit: Could also be manipulating other regional news/politics, but my instance is regional and doesn't subscribe to those which limits my visibility into the overall manipulation patterns.

What do these have in common?

1. Most are on instances that have signups without applications (I'm guessing the few that are on instances with applications may be from before those were enabled since those are several months old, but just a guess; they could have easily just applied and been approved.)
2. Most are random 8-character usernames (occasionally 7 or 9 characters)
3. Most have a common set of users they're upvoting and/or downvoting consistently
4. No posts/comments
5. No avatar or bio (that's pretty common in general, but combine it with the other common attributes)
6. Update: Have had several anonymous reports (thanks!) that these users are registering with an @sharklasers.com email address which is a throwaway email service.

What can you, as an instance admin, do?

Keep an eye on new registrations to your instance. If you see any that fit this pattern, pick a few (and a few off this list) and see if they're voting along the same lines. You can also look in the login_token table to see if there is IP address overlap with other users on your instance and/or any other of these kinds of accounts.

You can also check the local_user table to see if the email addresses are from the same provider (not a guaranteed way to match them, but it can be a clue) or if they're they same email address using plus-addressing (e.g. user+whatever@email.xyz, user+whatever2@emai.xyz, etc).

Why are they doing this?

Your guess is as good as mine, but US elections are in a few months, and I highly suspect some kind of interference campaign based on the volume of these that are being spun up and the content that's being manipulated. That, or someone, possibly even a ghost or an alien life form, really wants the impression of public opinion being on their side. Just because I don't know exactly why doesn't mean that something fishy isn't happening that other admins should be aware of.

Who are the known culprits?

These are ones fitting that pattern which have been identified. There are certainly more, but these have been positively identified. Some were omitted since they were more garden-variety "to win an argument" style manipulation.

These all seem to be part of a campaign. This list is by no means comprehensive, and if there are any false positives, I do apologize. I've tried to separate out the "garden variety" type from the ones suspected of being part of a campaign, but may have missed some.
