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.
Yes, and this would be fairly easy to make them at least pseudonymous without even needing to modify activitypub itself.
That said, I still don't support anything which lowers the friction of vote stalking like exposing votes in even more places. Technically people can look up my address from my license plate number if they really care to, but that doesn't mean I want to list it in bold letters on my windshield.
For starters datamining my voting patterns for building a deeper interest profile. It should be pretty obvious how this works in terms of user fingerprinting, and the ultimate monetization of Lemmy data. It would be super naive to think that Lemmy will be the one web space immune to this kind of thing. I guarantee you meta already has an army of silent instances doing this.
Worst case scenario, legit state actors use it to target deanonymization attacks at dissidents. I would not be shocked if the ...usual suspects... Are engaged in this kind of thing.
Incorporating that in a way that doesn't allow for vote manipulation by just lying to a server that different "anonymous" users have up or down voted a post sounds incredibly difficult, and not worth it for the narrow use case of "prevent my votes from being data mined even though all my comments can."
