IMHO I would s/If you piss us off by breaking/If you break/ - two thoughts:

1) This change might make it clearer that it's breaking the rules that will cause you to not be invited back, not breaking the rules to the point that we get mad (which I read as having a bit of wiggle room)
2) Obviously we want to sound serious here, but it reads to me a lot harsher than the rest of the computer-as-an-adjective text.
