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/gmbpjtmthttps://instance.xyz/u/tjrwwiifhttps://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?
- 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.)
- Most are random 8-character usernames (occasionally 7 or 9 characters)
- Most have a common set of users they’re upvoting and/or downvoting consistently
- No posts/comments
- No avatar or bio (that’s pretty common in general, but combine it with the other common attributes)
- Update: Have had several anonymous reports (thanks!) that these users are registering with an
@sharklasers.comemail 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.
Is there any existing opensource tool for manipulation detection for lemmy? If not we should create one to reduce the manual workload for instance admins
If there were, upbotters would use it to verify that new bottling methods weren’t detectable. There’s a reason why reddit has so much obfuscation around voting and bans.
I mean if a new account or an account with no content on it starts downvoting a lot of things or upvoting a lot of things that’s generally a red flag that it’s a vote manipulation account. It’s not always but it’s usually pretty obvious when it actually is. A person who spends their entire time downvoting everything they see, or downvoting things randomly is likely one of those bots.
Could they come up with ways around it? Sure by participating and looking like real users with post and comment history. Though that requires effort and would slow them down majorly, so it’s something that they’re very unlikely to do.
Good point, but is it then possible to come up with detection algorithms that makes it hard for upbotters even if they know the algorithm? I think that would be more ideal than security through obfuscation but not sure how feasible that is
I don’t know honestly. Really, with AI it would be pretty difficult to be foolproof. I’m thinking of the MIT card counting group and how they played as archetypal players to obscure their activities. You could easily make an account that upvoted content in a way that looked plausible. I’m sure there are many real humans that upvote stories positive to one political party and downvote a different political party. Edit: I mean fuck, if you wanted to, you could create an instance just to train your model. Edit 2: For that matter, you could create an instance to bypass any screening for botters…
