What Dragonfly said.
You stop them, they find another way. Every server has at least a few of them, but I feel a bit sorry for the smaller servers that get plagued with them, because the big servers are creationlocked most of the time so all the Bots, Gilsellers and the like flock to the smaller, open servers^^°
