you say victim-less crime? when someone purchases that copy or the KEY from that copy reenters circulation for purchase and they go to register it... It will say its already in use, hense its morally wrong and not at all victim-less. That is when they will call Blizz up explaining why happened, and there is a likely hood blizz will just take the key off the market by banning it. So yes SOME day the key may become void..
