So, PVHC's thread got me thinking. How does this work?

I've been on every boating message board there is, and other message boards too, since they appeared on the net...but I've never found myself being banned, placed in time-out, infracted, retracted, redacted....nothing.

Is it really due to pissing off a single person, or is it that some people just don't know when (or can't) STFU?

Which is it?
