It seems this person is playing on one server, best thing is to contact that server owner and send him/her the demo. Its definitely a the responsibility of TB to do anything about him. I didnt watch demo so Im not saying the dude is hacking or not. With no more PB its server admins that have to police their servers and ban cheaters unless server is running alternate anti-cheat like TZAC. Too bad our game is going to shit from all these kids hacking.
