I'm gonna use britny for this. Because it would take too long to explain absolutely everything.

This video is basically why I can't allow unban. No matter how many admins write here that you're not using cheats I'm gonna be against unban.
Also I have plenty of experience with aimbots. I was coding my own aimbot + I was in contact with a few cheat devs. I never made a mistake in bans where aimbot was involved. After I saw that 0:20 it was pretty clear that you're using an aimbot. I mean you can't even explain why you locked onto him and why it made that weird motion afterwards. You're an experienced player so it shouldn't be too difficult to explain why those motions happened. But since that motion after the lock is a bug you can't explain it even if you tried your best. Even private aimbots aren't perfect and can be detected easily if you know what to look for.
