I think the only practical solution is an old one, of using multiple spaces - a bunch of relatively closed spaces that you have to get invited to, with more open spaces that you might get invited from.
Closed doesn't have to mean secret, just that it uses a whitelist for who can post.

I have to agree. I don't think that 'global moderation' really works as a concept. What someone views as just a joke might be incredibly offensive to me. I have no problem with rape jokes or 9/11 jokes for example, but I never ever want to see any sort of gore, that's completely offlimits for me. Whereas some people (see 4chan) might not care about either, any many care about both.
