I don't know about you but this thread has loads of weirdness going on, and who knows how many scammers are on this thread. You have two newbies saying this guy scammed them. I bet notthepuma sold hackattack a bad card would be my guess, than maybe hackattack got desperate and tried to pawn it off on someone else. I had traded with him in the past too. So I'll give him a chance to explain whats going on before I judge, but all three are possible scammers

but we are only human and I've watched the most reputable people on this forum either default or straight up scam people after they themselves were scammed
