That’s an interesting thought, and could have some merit. Two issues I see with it - the first is that all instances would have to be on board. It’d have to be accepted and used across all Lemmy instances as a core Lemmy feature for it to be effective. The second is that some of those bad votes already fall into reporting territory. I don’t know what the reporting system is like on desktop but on my app it’s only a text box to report. Reddit had what I thought was a good system that was preset reports for site-wide and then subreddit specific rules. I think a robust reporting system (and again, maybe there is one or there’s one in the works) could handle spam, troll, or bot posts.

There is some academic research on internet voting system that aim to be troll and bot resistant and be overall better. There is a website that allow to vote for Youtube video here : https://tournesol.app/ . If you are good in mathematics, the research papers may be interesting.

That's a kind of voting mechanism that I'll love seeing implemented in the Fediverse
