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.

Edit: If you see anyone from your instance on here, please please please verify before taking any action. I'm only able to cross-check these against the content my instance is aware of.

As a regular user, I don't think there's much you can do, unfortunately (though thank you for your willingness to help!). Sometimes you can look at a post/comment from Kbin to see the votes, but I think Mbin only shows the upvotes. Most former kbin instances, I believe, switched to mbin when development on kbin stalled.

The solitary downvotes are annoying for sure. "Some people, sigh" is just my response to that. I just ignore those.

Re: Downvote bots. I can't say they're necessarily bots, but my instance has scripts that flag accounts that exclusively give out downvotes and then bans them. That's about the best I can do, at present, to counter those for my users.

It is usually not a good idea to specify what your exact metrics are for a ban. A bad actor could see that and then get around it by randomly upvoting something every now and then.

True. But it uses a threshold ratio. They'd have to give out a proportional number of upvotes to "fool" it, and at that point, they're an average Lemmy user lol. That script isn't (currently) setup to detect targeted vote brigading, just ones that are only here to downvote stuff. I've got other scripts to detect that, but they just generate daily/weekly reports.

It takes time to detect them, but it does prevent most false positives that way (better to err on the side of caution and all that).
