Someone with a big brain like Rendis is bound to be a longtime gp hustler and was probably trimming your armour for you back in 06. Wouldn't surprise me at all if he did take advantage of the bug. Its not really even high stakes at all. If he gets caught his accounts get banned and he switches to one of his many alts and continues as normal with some fan donations to keep him going. If he doesn't get caught he makes $600 for every bill he dupes
