I think at one point there was discussion of a +vampire command that would suck away 2xp from every player...  The opposite of our confetti command that admins use to randomly distrubute XP for birthdays, lots of people logged on, those rare occasions when we're in a good mood, or, in my case, finishing the bar exam, etc.  

I don't think we ever carried through on the XP-sucking threat, though.:)  The players would take to the barricades.  As Brody said, we just ask people nicely to vote, nowdays.
