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??
A chain/tree of trust. If a particular parent node has trusted a lot of users that proves to be malicious bots, you break the chain of trust by removing the parent node. Orphaned real users would then need to find a new account that is willing to trust them, while the bots are left out hanging.
Not sure how well it would work on federated platforms though.
I don't think that would work well, because I knew no one when I came here.
You could always ask someone to vouch for you. It could also be that you have open communities and closed communities. So you would build up trust in an open community before being trusted by someone to be allowed to interact with the closed communities. Open communities could be communities less interesting/harder for the bots to spam and closed communities could be the high risk ones, such as news and politics.
Would this greatly reduce the user friendliness of the site? Yes. But it would be an option if bots turn into a serious problem.
I haven't really thought through the details and I'm not sure how well it would work for a decentralised network though. Would each instance run their own trust tree, or would trusted instances share a single trust database 🤷♂️
