Comment on Private voting has been added to PieFed

While not a perfect solution, this seems very smart. It’s a great mitigation tactic to try to keep user’s privacy intact.
Seems to me there’s still routes to deanonymization:
- Pull posts that a user has posted or commented in
- Do an analysis of all actors in these posts. The poster’s voting actor will be over represented.
- if the results aren’t immediately obvious, statistical analysis might reveal your target.
Piefed is smaller than lemmy, right? So if only one account is voting somewhat consistently in posts where few piefed users vote/post/view, you got your guy.
Obviously this is way harder than just viewing votes. Not sure who would go to the trouble. But a deanonymization attack is still possible. Perhaps rotate the ids of the voting accounts periodically?

Not familiar with how piefed handles it specifically but aren’t posts/comments self-upvoted by default?
You could probably figure it out pretty easily just by looking at a user’s posts, no?
(This is unless piefed makes it so the main actor up votes their own posts, and the anonymous actor upvotes others’ posts, but then it would still be possible to do analysis on others’ comments to get a pretty accurate guess)
