The best part of the fediverse is that anyone can run their own server. The downside of this is that anyone can easily create hordes of fake accounts, as I will now demonstrate.

Fighting fake accounts is hard and most implementations do not currently have an effective way of filtering out fake accounts. I’m sure that the developers will step in if this becomes a bigger problem. Until then, remember that votes are just a number.

    This was a problem on reddit too. Anyone could create accounts - heck, I had 8 accounts:

    one main, one alt, one “professional” (linked publicly on my website), and five for my bots (whose accounts were optimistically created, but were never properly run). I had all 8 accounts signed in on my third-party app and I could easily manipulate votes on the posts I posted.

    I feel like this is what happened when you’d see posts with hundreds / thousands of upvotes but had only 20-ish comments.

    There needs to be a better way to solve this, but I’m unsure if we truly can solve this. Botnets are a problem across all social media (my undergrad thesis many years ago was detecting botnets on Reddit using Graph Neural Networks).

    Fwiw, I have only one Lemmy account.

      I see what you mean, but there’s also a large number of lurkers, who will only vote but never comment.

      I don’t think it’s unfeasible to have a small number of comments on a highly upvoted post.

        Maybe you’re right, but it just felt uncanny to see thousands of upvotes on a post with only a handful of comments. Maybe someone who active on the bot-detection subreddits can pitch in.

          I agree completely. 3k upvotes on the front page with 12 comments just screams vote manipulation

            True, but there were also a number of subs (thinking of the various meirl spin-offs, for example) that naturally had limited engagement compared to other subs. It wasn’t uncommon to see a post with like 2K upvotes and five comments, all of them remarking how little comments there actually were.

      Reddit had ways to automatically catch people trying to manipulate votes though, at least the obvious ones. A friend of mine posted a reddit link for everyone to upvote on our group and got temporarily suspended for vote manipulation like an hour later. I don’t know if something like that can be implemented in the Fediverse but some people on github suggested a way for instances to share to other instances how trusted/distrusted a user or instance is.

        An automated trust rating will be critical for Lemmy, longer term. It’s the same arms race as email has to fight. There should be a linked trust system of both instances and users. The instance ‘vouches’ for the users trust score. However, if other instances collectively disagree, then the trust score of the instance is also hit. Other instances can then use this information to judge how much to allow from users in that instance.

          This will be very difficult. With Lemmy being open source (which is good), bot maker’s can just avoid the pitfalls they see in the system (which is bad).

      On Reddit there were literally bot armies by which thousands of votes could be instantly implemented. It will become a problem if votes have any actual effect.

      It’s fine if they’re only there as an indicator, but if the votes are what determine popularity, prioritize visibility, it will become a total shitshow at some point. And it will be rapid. So yeah, better to have a defense system in place asap.

      I’m curious what value you get from a bot? Were you using it to upvote your posts, or to crawl for things that you found interesting?

        The latter. I was making bots to collect data (for the previously-mentioned thesis) and to make some form of utility bots whenever I had ideas.

        I once had an idea to make a community-driven tagging bot to tag images (like hashtags). This would have been useful for graph building and just general information-lookup. Sadly, the idea never came to fruition.
