Looking to maybe self host my own instance, I’m still learning about the fediverse. If a different instance that I federate with hosts something illegal are there risks to me? Is anything from other instances hosted on my server like a copy of it? Or would I only end up hosting things my users post? I’m paranoid and sorry if this is a silly question.
The Electronic Frontier Foundation wrote a pretty good blog post on the legality of the Fediverse, around the time Mastodon was getting popular. It probably applies to Lemmy too. It’s worth a read to familiarize yourself of what kind of legal things you’ll be getting yourself into. You’re on the right track; you can control you and your friends’ content, but you can’t control remote content that gets pushed to your server and that’s the part to worry the most.

One thing that stood out is to register yourself as a DMCA agent. It costs $6 or something. Having an agent on record gives instance admins certain protection.
