The reason for your ban is:
psychomicron Suspected Cheater - 75 % HS DMR [Auto-Admin] \
That's not serious at all.
If I got high % of head shots in 1 of 100/200/300 rounds, doesn't mean I use "cheats" . This does mean I'm a good player with great reaction + great map for me + did most headshots from close distance + was lucky. This is clear for every normal gamer.
Best Wishes,
Have fun guys
