As to being booted/whining about unfair play/etc. "My house, my rules." Besides the usual control over vulgarity, racism, etc, I think it ought to be left the way it was. If I'm host, I do as I like. If you don't want to deal with it, I'm not forcing you.
It was a riot to be able to create freak universes with crazy colors and wacky physics just to let off steam with my friends. Cutting off that ability to make others feel better would be rather irritating.
