So. I thought about the potential of bad actors sniffing on lemmy data. In theory, you’ld have to trust your lemmy-instance hosted to not be a bad actor and every single server they federated with. That means, it should be really - REALLY - easy for a bad actor of even a nation state actor to set up an instance and just wait for the data of users to pour in.
Theoretically they could see all the posts you ever made, and, every post you upvoted. Which also gives clues on: When are you active, what region are you from, etc.
I mean - Maybe I’m too suspicious but tbh the more I read into this, the more I get a bad feeling about this…
Yes. When you like or dislike something it gets synchronized with different federated servers. Which means, federated servers have a database of all your likes and dislikes, and even your posts. The server admins of that server have, by nature, the password for the database and can therefore track every move you make. Just one “Bad guy” that has a server that is federated with your accounts server and they will know a lot about you. And since its open source theoretically everyone can do this. Criminals, Stalkers, Governments, Companies, everyone.
