Banned?

[Bullitt]

Hey Piglet,
For some reason when I join a game it kicks me out and says I've been banned for the rest of the game. Hopefully I haven't done anything wrong. If so, I'd like to know what. It's happened twice now. Thanks

If you reach more than -13 points in one game you will be automatically kicked.

-13 ? Now I know why 13 is an unlucky number ?
