I think all the people that want questionable content legally hosted to do it their damn selves and learn the consequences of that choice or shut the hell up.

This is overkill, just don't host anything you aren't comfortable with, and let people go make their own for anything you aren't. That's the entire point of defederated design. Ignore the idiots who think this is reddit and are screaming about censorship and let them go deal with the headaches involved by making their own places. Signed a fellow sys admin of many years who actually knows what this is like.
