I get that he very well likely did many of the things that are claimed of him. The problem is that while it is said he went so far as to threaten you Wayne, I also see in this very thread a physical threat against him. As I understand it, he was banned because the kind of nutbaggary that would make physical threats are not the kind you want here. I would agree with that, but the rules against threats seems to only apply to those that the mob has decided they don't like.
There are definitely nutcases on this board. Heck, one might argue that hanging out on this board pretty much defines you as a nutcase, but the viciousness on this board gets REALLY bad, and a blind eye is turned when for some people, while the TOS bets broken out for others.
The comments made against "Mr. Campbell" go far beyond warning against doing business with the guy. They are incessant, and personal attacks. They set the bar pretty low for what is considered acceptable behavior, and they are frequently exactly what some of the claims against him are.
I realize that many of use were in high school when we were first introduced to the Amiga, but we are not any more. We should act like grown ups. OK, maybe not grown ups. But we should at least be civil.
