I see not a single thing that looks toggle/aimbot at all. Twitchy people exist and they play shooters so it makes it a little fishy looking sometimes.

9000 - Teammate just died from that location. Situation awareness and sound.
9800- He sees the first T before he starts shooting. Reaction time, bad aim.
12500 - Sadly enough, people dont understand that the head box is typically going to be in the same spot because most people dont crouch or jump early in the round. Play long enough and you know where to aim especially that early in the round knowing people will go that way. Reaction time.
18500 - He popped up and there was a head. Reaction time.
19100 - Reaction time. Also sound.
20000 - He is simply screwing around, it is a game after all. Once he actually leave the corner and engages, he shoots where he last seen an enemy while the other enemy comes from the left and his reaction time wins. He sprays around because he has a P90 with lots of bullets and is a camper so he shoots spots he would be (I assume.) Since Samira wanted to knife she did not return fire and he was able to kill her.

Nothing here as far as I am concerned but I am a lowly admin with no power in this realm. Judge it as you may, Yushun is a camping baddie all day but this does not prove he uses aimbot.
