Actually I think I know why I was banned but I'm not really sure 
Actually, I have a Logitech g502 and I thought it was a genius idea to shoot with the mouse wheel. I remember when I was 12 years old, I was messing with my Xbox 360 controller to shoot at that speed.
If this is outlawed I'm sorry, I didn't really think it through.
Only I have a trainer for the offline zombie mod. Is it possible that this is the reason for the ban ?
Please Help
