I checked your chat and while I can see you warned someone for "map exploiting" it wasn't the person in the demo, and saying map exploiting isn't really clear to anyone reading that you mean door spamming. The guy in your demo seemingly gave up shortly after you began your demo so it seems like he was just screwing with you guys more than anything. Don't think a ban should be issued in this case, but we'll keep an eye out for him in the future.
Thanks for the report,
