Social media platforms like Twitter and Reddit are increasingly infested with bots and fake accounts, leading to significant manipulation of public discourse. These bots don't just annoy users—they skew visibility through vote manipulation. Fake accounts and automated scripts systematically downvote posts opposing certain viewpoints, distorting the content that surfaces and amplifying specific agendas.
Before coming to Lemmy, I was systematically downvoted by bots on Reddit for completely normal comments that were relatively neutral and not controversial at all. Seemed to be no pattern in it... One time I commented that my favorite game was WoW, down voted -15 for no apparent reason.
For example, a bot on Twitter using an API call to GPT-4o ran out of funding and started posting their prompts and system information publicly.

Bots like these are probably in the tens or hundreds of thousands. They did a huge ban wave of bots on Reddit, and some major top level subreddits were quiet for days because of it. Unbelievable...
How do we even fix this issue or prevent it from affecting Lemmy??
Captcha is already mostly machine breakable, I've seen some new interesting pattern-based stuff but nothing that you couldn't do image training against.
At some point not too far in the future you won't be able to use captcha to stop bots from posting. It simply won't even be a hurdle, a couple extra pennies of computational power.
There's probably some power in detecting accounts that are blocked by many people. The problem is no matter what we do we're heading towards blocking them with an algorithm or AI. And I'd hate to see that for Lemmy.
This place is just the stuff you follow with the raw up and down votes. We don't hide unpopular posts making brigading less useful.
I feel like the real answer is and has been for a long time some sort of distributed moderation system. Any individual user can take moderation actions. These actions produce visible effects for themself, and to anyone who subscribes to their actions. Create bot users who auto-detect certain types of behavior (horrible stuff like cp or gore) and take actions against it. Auto-subscribe users to the moderation actions of the global bots and community leaders (mods/admins) and allow them to unsubscribe.
We'd probably still need some moderation actions to be absolute and global, though, like banning illegal content.
