What really interests me is, how I can host a PeerTube instance, without getting into all sorts of responsibility issues, like people uploading videos containing illegal stuff (upload filter laws). I would love to give my server something to do, but with the current law, I simply do not want to be responsible for what people upload and spread via my instance and my server. Does PeerTube offer me a way of reviewing videos before they can be found and a way of telling people, that they are responsible themselves and have that accepted by law? And how do other instance admins manage this? Does anyone here have that experience?
I think the usual approach is similar to any other service hosting: don't do open registrations unless you feel like dealing with the moderation and legal consequences.
Have a contact form where people can request an account. Create accounts for trusted peers. I'm unaware if Peertube has a "moderate first" setting but it should not be hard to implement... it's just not the assumed usecase of Peertube so far.
