Microsoft has claimed before that players who modify their Xbox 360s will be kicked off of the Xbox Live network, and today, followed up on that promise.
Modifying the console is against the Live terms of use and a number of subscribers have been banned for it.
Microsoft refuses to reveal how many of its 20 million Xbox Live player base has been given the boot, but rumors from the internet speculate it to be about 600,000 people, or 3%. The company also refused to note if the kicks had been made over time or very recently.
So let this be a note to anyone considering modifying their consoles: Microsoft, at least, truly will not stand for it.
