A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

Mastodon thinks Lemmy’s privacy stinks. What say you? (raddle.me)

Federated services have always had privacy issues but I expected Lemmy would have the fewest, but it's visibly worse for privacy than even Reddit.

  • Deleted comments remain on the server but hidden to non-admins, the username remains visible
  • Deleted account usernames remain visible too
  • Anything remains visible on federated servers!
  • When you delete your account, media does not get deleted on any server

I thought votes didn't federate yet anyways... but, yes, it is possible, and i can come up off the top of my head with three or four potential implementations.

Good luck with finding an anonymous system that can not be easily abused.

FHE solves that through and through, as has been documented widely, but that's overengineering when you could just use plain ZKP.
Zero-knowledge voting is here and has been for a while now.
