The Association of Copyright for Computer Software (ACCS) led an investigation on the case, and revealed that the culprit had many happy customers; comments such as "My children are happily playing away" appeared on his Yahoo! Auctions feedback page.
Two things that stand out about this story: the sizeable wad of cash this guy managed to generate before being caught, and his apparently respectable position in society -- according to the ACCS, he runs (ran) a cram school. We're guessing neither activity will feature heavily in his immediate future.
Update: Added further clarification.
