So, why not install one of the members there as mod to clean up the rule (which has never been enforced). As it is, it's been nuked - the community name is banned forever, and the members are sol.
edit: The community was deleted less than an hour after this thread went up, there was no effort made to correct the problem whatsoever.
If it's against the rules to be unmoderated, there should be a way to add mods, since there's obviously no way for the current non-existent mod to do so.
