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’m also not sure how it’s enforceable in a distributed system.
Blockchains have the property of being append-only, so a blockchain is precisely what makes it impossible to delete transactions. That being said, in a distributed system, once the message leaves trusted servers, it is obviously also impossible to delete it.
Nothing about how lemmy or the fediverse platforms work has anything to do with blockchains. Don’t conflate “decentralization” to include blockchain. Torrents are also decentralized and have nothing to do with blockchains.
Why are you bringing up blockchain?
Lovely, the parent comment mentioned blockchain but was since edited… Trust me I would not have brought it up otherwise.
