The reason why he is leaving is because he has gotten banned for using Wallhacks.
Don't try to deny it , you are leaving right after the ban , if you had gotten banned unfairly you would surely make an unban appeal , but you have chosen to admit it in a way of leaving.
Unnecessary Story ahead :
My suspicion started a few days in texaswood map , when only 2 T's were there , you did a HnS day and you just kept on roaming around the area I was at checking it a trillion times hoping for me to maybe pop out or something , your patience finally ran out and you made the stupidest excuse ever , "I heard a footstep" , but I was quite sure I did not make any sound because I was crouching and there was no way I could jump or do anything to create sound unless I slashed or stabbed and that's when my suspicion started , I tried to spec you a few times but had no luck twice but the third time you just wished to go YOLO and completely showed us that you're using wallhacks.
It's no ones fault if you wallhacked , you can admit it on the unban appeal topic and maybe get a temporary ban of 3 months.
But if you're leaving then , good luck with everything and stuff.
