In my case I would like them to be private, but currently they are not. I don’t think it is good to try to hinder the visibility into a fundamentally transparent system.
I don’t see a technical way to make votes private either, that doesn’t prevent bad actor instances abusing the vote system. As an admin of an instance I could just add 5-10 votes to all of my interactions whenever I feel like it, and noone would be able to tell it didn’t come from legitimate users on my instance. The accounts of vote origin are needed as proof, hence moderators on lemmy having access to them.
Do you perhaps have any idea how this could be accomplished?
