Maybe Badspot believes that some people can learn from a ban?
I can see that in cases where someone doesn't follow the rules and gets banned for it. They make sure not to break the rule again.
I'd think that the reason why people get permanently banned when they break Rule #5 is that they have no desire to be a good member of the community anymore, and that any further access to the forums would just give them a reason to break more rules/get revenge for being banned.
You might be right though. I don't think Stocking is going to spew any more of this anti-homoloveual garbage anymore, since all she ever does is post on the forums.
