Aye, as paul says, most people buy them without even realizing the damage they do, and without knowing their risking masive fines or even going to prison. The big firms, ie Game, Gamestation or not that effected. Its the little guy that runs his own shop where it hits the hardest.
Piracy has allways, and will be a problem, I just saw red when some one is openly selling them on a popular public forum.
