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, what you like and dislike (obviously), political views, 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…
There’s nothing you can really do about it. Lemmy should encourage as much privacy as possible, and it’s plain to see that there is work to be done in that realm, however, you should always protect yourself from the servers you connect to and store data on, regardless of whether it’s oriented to privacy or otherwise.
Using VPN or TOR, not saying anything that could identify you, making multiple accounts, things like this.
