True, but if you really want to strike back at the scammers, a better way is to sell the scam coins right away when the scammer is creating a fake market by both buying and selling. Creating an order fee is a lot lot less (0.00092 BTS), and the scammer will pay BTS to buy their own crappy coin. E.g. http://cryptofresh.com/a/QVANTUM
