Actually, Matt, I think that some times you are too fast at slapping people that come on board. Maybe you have tools that tell you a new poster is a nuissance because he was a nuissance under another "handle", but even if an habitual "offender" comes in and post less than virulent posts, you don't give them another chance because of their prior sins. Let them at least do something very wrong before you boot them. Forgiving is a virtue after all....
