Looks like it can be done, and I agree that it could be useful. ATM, us poor users can do nothing but click "report post to moderator," and then they can't do anything either until one of the supermods wakes up.
Actually, thanks for dealing with it quickly. Those posts were really starting to get annoying. Perhaps vBulletin could do with a feature to detect users making many identical posts, and shout at them automatically instead of RHS having to do it.
