[Help] no spread - no shake?

Hello. I'm new on this forum, so sorry if I'm doing something wrong.
I know one guy, who 100% cheating and he's playing like a clean person.

Look at this clip. You can see it's obv hacked (i'm sure he's cheating, there is no - no.)
He's not shaking, or something. Also it's not metori, cuz he's playing on all servers and still shooting s@!t.
Can it be no spread - no shake or something? I checked everything, I know a lot cheaters like him on my country. What they're using? One guy told me that is private hack from aiwnjoo or something, maybe he's just trolling.
So my main question is: What he using and it's possible - no spread no shake?

Thanks for replies.
