Exactly, being able to blacklist them from entering at all would be a simple solution to this problem. And I know for a fact we are not the only RP venue with this problem. Every venue has their blacklist, but what does that really mean? Since we can't keep them from coming, they can just enter and annoy people even if they've been "banned." Just make a blacklist for the house, and if they're on there they just can't enter at all.
