I noticed that there were some accounts that were hijacked by the instance owners. All the posts from that user were then edited to say what happened.
This kind of surprised me, I figured instances could delete posts, but not edit them. So how much control do they have?
I assume they can’t see my password (hopefully). Can they post in my name? Do they have all the access to my posts to foreign instances that they do over local posts?
Edit: thanks for all the responses everyone! I’ve wanted my own instance for a while, but maybe I’ll get on it now
as instance admins, they have access to the database, so they straight up can edit any data.
only thing they can’t do is view your password (hashed), but they can replace the hash by one of a known pw.
so you must have some trust in your instance owner, again whats good with the fediverse is that you can just start your own instance, and then the best they can do is defederate from you or ban you.
