I remember the conversation pretty well.  The thing that probably got this guy upset was I told Unreal to find me proof.  If he did find some that we agreed on on he would of course get banned.  The optimal thing is proof.  The fact that he put a link to the correct demo that he was accused on is tellin me there is nothing there but the demo should be viewed to see for sure.   If there is no proof in the game he was accused on then he should be vindicated and if Unreal harasses him in the future he should be warned first and then dealt with if he continues.  That would make this situation go away.
