Yes, that number actually represents a year...

So what gets someone banned from Xbox LIVE for 9999? One individual found out the hard way, though that's not to say he didn't deserve it.

User TC57UK went on the official Xbox 360 forums with a question about his son's account, which he noticed had an unusual date attached. Says he:

"Hi, Posted earlier about my son's suspension and no help. Then i realized did not put his gamertag in the message. i am BlaaaacK v is his gamertag. Would be helpful if someone could enlighten me as to why he has been suspended until 31/12/9999 without notification."

Well, a helpful Xbox LIVE policy-enforcer dude did answer TC57UK. Several hours after the initial inquiry, XBLPET Whiskey replied with an unexpected yet hilarious answer. Just check out the image; the response is too funny to even type out.
