I haven't had to ban anyone yet, which I'm happy about. But I won't hesitate to do so if it needs to be done.

But, most of my members are people I know. So I guess that's the reason why I haven't had any trouble. Plus, most newbies just come through during the board hops, post a few times and never come back. Or they wait and come back during another hop just so they can advertise their board(s).
