Trying to wrap my head around the fediverse. Is each instance like another person with a server? Could that person just shut it down whenever they wanted to?
Are there any companies that have invested in hosting Lemmy/ other fediverse servers?
Sorry I’m sure I messed up some of the terminology, I hope my questions make sense! I love the idea of the fediverse as I understand it, but I like to dig into these details.
It’s a bit more than that, when a client connects to lemmy they connect to all instances with displayed media. This includes thumbnails. Even inside a post, you’ll connect to every user’s instance to get their profile thumbnail. This could be quite exploitable, as the federated instance is always the user’s instance, not the instance of the community they post in - it would be possible for someone to fish for IP’s by setting up their own instance and posting on a popular community.
/u/sunauras@lemm.ee is making a new UI that apparently handles all these calls a different way, without connecting everywhere. It’s still a work in progress (you can’t comment there yet) but it looks promising.
Thanks. Lemmy’s privacy story is actually kind of bad. Like if you read a post, the instance retains that fact, to support features like “show unread posts”. But that means not only is your posting history public, but your reading history can potentially be exposed.
That’s the main reason I sometimes think of running my own instance. It would receive all the posts from every community without revealing which of them I bothered looking at.
