So what exactly is it that gets you banned for such a long period of time?
An UNO player has been banned from Xbox Live until the year 9999 for exposing himself online.
And it was the way the wrong-doing was, ahem, exposed that's likely to cause him even more grief than simply being banned.
Xbox Live user TC57UK asked why his son was banned until 12/31/9999 and Xbox Live moderator XBLPET Whiskey replied "your son was exposing himself on camera in Uno."
Ouch. Still, if he somehow makes it to the year 9999 and his Xbox 360 is still intact and Microsoft keeps the servers running, at least he's got 7000-odd years of gaming to catch up on!
