honestly, getting banned for high stats is funny. In stats you cant see a difference between an good or an bad player. KD = can be reached by camping 24 / 7 with bipod in corners. SPM = taking Flags, reviving others. (Ez to have SPM over 2000 with 200% Boost for example) KPM= not hard to play high KPM in TDM mode. On Locker 64 players it isnt hard aswell to have KPM over 3. He isnt playing vs Tryhards atm, because it is anoying. (but this aren´t something to discuss in here). i am one of mates who playing together with Bunny every day and we reviving ourselfs, thats why we have good rounds. We playing in a Squad. Back to my 1st Part. If someone have high Stats against Casual players or Tryhards, thats a point you cant see in stats you know what i mean?.
This Screenshot where you can see him on the roof of C Tower. Any Proofs you can it was him? no, what i mean is you cant see who was the player who spawned or glitched (idk) on the C roof. no reason to get banned. i can tell you why everyone says he is cheating: easy to explain. Noob get farmed by himm he dont have any chance because Bunny is the better player. Noob see his KDR on server and crying about cheating. Just a normal day.
And same as Matti said before: every good round he played was uploaded on YT, just check it.

As my last word to this appeal: he is a legit player who only know how this game is working. Much Time in games and experiences in playing comp matches is the way to be a skilled player.
