Hmmm, anyone want a double or over verification system? Like, when you buy, it asked you to put in a verification question and answer? It'd ask the person using the code the question and they'd have to answer :o If they got it right, they'd be verified. If not, 2 more chances, then kick off for 30 minutes.
Also, rename to topic to "My key was stolen" because this topic is too abm...abm....whatever
