My opinion on what you just said. But let's not resort to ad hominem.

Cyber bullying = bullying.

If I kill you wearing a top hat, we should ban top hats, because that's the reason you got injured, huh?

If I kill you using a sledgehammer, then it's the sledgehammer's fault, not mine.

Sure, the sledgehammer made it easier, but it's still my fault, isn't it?

The net is a means to an end. You can help others, harm others, annoy others, argue with others, among many things.

Oh, and according to logic, which you yourself stated should be used, this post isn't going to do anything.

EDIT: Everything can be a more courteous place. This doesn't only apply to the net, WoW, or anything specific at all.
