It's believed that up to 600,000 gamers may have been cut off from Microsoft's Xbox Live online gaming service because they're running modded consoles that can play pirated games.
Microsoft has confirmed that "a small percentage" of Xbox's 20 million users had been banned. By our calculations, that'd be 3%, which seems quite a large number for a process that involves opening up the case of the console and - in many cases - soldering in a new chip.
