Congrats on reaching this set of sane rules. The efforts of creating an admin community behind the scenes are really starting to show off.
Request for clarification for uhmm, a friend of mine: When someone creates that own instance, with blackjack and hookers, and one of your users subscribes to a community there, it will synchronise part of that content to lemmynsfw. What will you do then?
I'd like to remind you that some beautiful maniacs can be quite reasonable ;)
