You can do what you want, it's an honesty sport, filed with honest players. If your really paranoid, go for it. (Assuming you have the required licenses) just make sure you listen in on your team's main channel or admin channel for alerts and emergencies, and don't be a douche and listen to the other team's channels or you'll get ejected from the game, and nobody will want you around in the future. Again, back to the honesty thing.
