I know this guy , he is a really nice guy. I have talked with him in steam about this , he said that it was his first time that he used wh and i believe him since i have played with him many times. Dont act like he has comited a crime , its just a game , he admitted it straight away and he is begging to forgive him. Im not saying that you should unban him but at least ban him for some months and not permanently. I never supported anyone who has used cheat , but i know this guy and im 100% sure that he will never use any kind of cheat again.
