@chiasm I've come across this post but I haven't spent much time going into it.
I run an instance for myself, so the problem with harassment on a server doesn't come into play. With regards to if illegal content could end up on the server I suppose that is a possibility, but it would be easy for me to remove upon request.
But it would also be hard for someone to find it because they would essentially need to know the direct link to the offending content. And that's hard without an account...
