The problem isn’t keeping votes anonymous, that’s easy. The problem is bots/spam. You could just create a new instance and then upvote a post from another instance a thousand times. If the votes are anonymous for the other instance it’s tough to say if they are genuine users or just bots.

That’s the main issue here, when votes are anonymous you could easily just spam votes with no way to trace it back. If it’s a rogue instance then fine, you can ban the whole instance. But imagine if lemmy.world starts using fake votes in the background towards other instances.
