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 they act like I assume most users do. I upvote people I reply to etc)
- if the results aren’t immediately obvious, statistical analysis might reveal your target.
Piefed is smaller than lemmy, right? So if only one targeted posting 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?
Yea, I agree. It’s good enough. Sorry, I didn’t mean to sound like it was a bad solution, it’s just not perfect and people ought to be aware of limitations.
I used a small instance in my example so the problem was easier to understand, but a motivated person could target someone on a large instance, too, so long as that person tended to vote in the posts they commented on.
Just for example (and I feel like I should mention, I have no bad feelings towards this guy), Flying Squid on lemmy.world posts all over the place, even on topics with few upvotes. If you pull all his posts, and all votes left in those posts from all users, I bet you could find one voter who stands out from the crowd. You just need to find the guy following him everywhere: himself.
I mean, if he tends to leave votes in topics he comments on, which I assume he does.
It would have to be a very targeted attack and that’s much better than the system lemmy uses right now. I’m remembering the mass tagger on Reddit, I thought that add on was pretty toxic sometimes.
Also, it just occurred to me, on Lemmy, when you post you start with one vote, your own. I can even remove this vote (and I’ll do it and start this post off with score 0). I wonder how this vote is handled internally? That would be an immediate flaw in this attempt to protect people’s privacy.
