This sniper https://steamcommunity.com/profiles/76561198964363279/ <-- steam link hasnt missed any headshots for 3 rounds straight and always kills his targets within 1-3 seconds upon looking at them. Im pretty sure this is a cheat because in all my years of tf2 ive never seen a machina sniper get kills like this. He even managed to kill a jumping scout in 1 second upon aiming.
