Nintendo has long struggled with counterfeiters. And for the most part, they're (generally speaking) faceless/nameless denizens who hide in the shadows of the internet and are difficult to track down.
But every once in a while you get a Justin Success-Brooks, who just pled guilty to selling counterfeit Nintendo DS games; his schemes earned him both close to a million dollars in profit, plus over two and half years behind bars.
According to Joystiq, Success-Brooks was no ordinary counterfeiter. The man was tried and convicted of selling faked games through a whopping 18 different websites, and was aided by several dealers in China.
At one point, Nintendo caught on and warned the man to stop or face severe consequences. Those cease-and-desist letters were all ignored. Even after having his stock seized, he continued forth with his activities, just via different website.
Success-Brooks' operation has been described as "complex and sophisticated." The prosecutor in the case, Francesca Levett, also states: "The damage that this has done to the reputation of online retailers is untold and incalculable."
