This was a message sent to a player who got banned for cheating.

“Because you used modified data to connect online, you’re now banned. The ban will be lifted at 22:49 on 12/12/9999. In the future, if you violate the terms of service, it is possible that you will be banned for good.”

I’m not sure if it is a bad translation or if the person really is going to be banned for another 9990 years?
