The Aimbot isn't really a friendly so to say but anyway, the aimbot is more of a cheat/script to use rather than an actual type of player. Most of the time they are seen playing sniper and killing you from across the map. Good ways to tell an aimbot apart from simply a good sniper player is the following:
*They are more often than not spinning fastly and crouching.
*They are often seen flick sniping as soon as they see a player around.
*They are often seen spamming in chat or being named really edgy and shit like: the n word, ( ͡° ͜ʖ ͡°), and more. (Or they might take the name of another inoccent player. perhaps trying to shift the blame on the inoccent player.)
*And some of them have Noise maker Particles around them.
WHY AIMBOTS THO? JUST WHY?!
Probably the reason why aimbots do this it's not beacuse they are assholes without skill, but beacuze they are attention whores. We all go through that stage in life that you are just a bother to everyone you are with it's called being an: "Absent minded little shit".
