I dont think it is possible to detect it, without watching the player in spectate. That aimbot is a third party mod for the game, the only way for you to detect I think is by a player reporting it, or what ever. you might be able to run a timer, and see how fast a player kills a certain amount of people, then it can send a message to all the admins warning them that "john has killed x amount of people withing 5 seconds, hack suspected: aimbot" for example...
If that makes sense
