I can't remember why he was banned and I don't see any point in bringing up old drama so lets just leave it be.
He did code the first store hack for vB2 although you won't find it here any more. I remember the source files begin mostly comments though...don't ask me what they said...the swear filter would probably catch it anyway.
IIRC there were multiple exploits in that hack aswell..I can't remember if they were ever fixed by the author or not.... With that said..under the current policy I hope no one goes looking in the vB2 forum for old bugs >.> Bound to be a lot of them..
