Currently, almost anyone in the Fediverse can see Lemmys votes. Lemmy admins can see votes, as well as mods. Only regular Lemmy users can’t. Should the Lemmy devs create a way to make the votes anonymous?
There is a discussion going on right now considering “making the Lemmy votes public” but I think that premisse is just wrong. The votes are public already, they’re just hidden from Lemmy users. Anyone from a kbin/mbin/fedia instance can check out the votes if they are so inclined.
The users right now may fall into a false sense of privacy when voting because the votes are hidden from Lemmy users. If you want to vote something and not show up on the vote list, please create another account to support that type of content and don’t tell anyone.
I’d even argue public votes can deescalate some situations, for example where both sides of a relatively heated discussion can see they vote each other up. They don’t necessarily agree but they appreciate the other side’s points.
As for the transparency, it’s not possible to list all the votes of a user, one rather needs to list votes on a given post. To profile a given user the attacker would need to cross-reference the data from all posts and comments which is computationally infeasible, both client-side and server-side.
