Had this guy on our rush server www.bf4sf.com the other day. I lost the battle reports but he had a very high k/d. I switched to spectator and he started playing much worse. I managed to get some video of him before he left in the middle of the round and went to another server.

His stats alone are very suspicious. Good luck, happy hunting!
