@Hex: That is a good suggestion. Thanks!
@Karalyn: I agree about egregious violations. The current CoC states:
In general, a "3 strikes" policy will be in place for the purpose of enforcing forum rules; for a first offense, a warning will be issued - it is your responsibility to educate yourself to avoid the mistake in the future (the Educate Me 101 forum is, again, a good place to do this); for a second offense, any action from a warning up to a suspension (for some length of time to be determined on a case by case basis) may be applied; a third offense will, in most cases, result in that user being banned from the forum. Be aware that in the case of hate-mongering, moderators have the right to ban a member outright.
So I think the notion that the outright-ban has always been an option is there, but is, at this point, a bit too implicit. So I agree that we should make it more explicit.
It also seems to me that we've already had something of a "plan of action," and what was missing during the recent meltdown was one or both of two things: 1) Having enough mods around to catch issues like that as they happen, so forum members are left to hold down the fort. 2) Having a clear-cut set of guidelines as to who, exactly, is responsible for enforcing the plan. I've been working under the assumption that it's firstly the dedicated mod, secondly all mods, but again, making that (or whatever we decide on) explicit seems necessary at this point.
