No
I find the user to be legit, from the very first rounds it's apparent the user is NOT shotbotting, multiple of times you see the enemy pass through his crosshair and no shot is made. The user has naturally good aim for aslong as I can remember going back years, regardless of this for me he's legit, there no signs to indicate him of using anything. Shots made are made withing the appropite hitbox region, there's no pellets curving to suggest a form of aimfix and as mentioned above there's no signs of a shotbot in use.
Also 90-10 is easily done.
