gore_ yeah i didn't know what you meant by that trickshot last kill thing but since you offered it as something that you were doing when you got banned, i just wanted to clarify... 
I'm not trying to say that you are necessarily lying, i'm just saying i've never known the staff to take a banned person's "word for it" and reversed a ban... they know how the anti-cheat works and i'm sure have logs that can tell them much more info than what us normals are privy to!
I absolutely disagree that this is "clearly an issue" because if there was a rampant issue of false positives, you would see A HELL of a lot more people complaining about it compared to the VERY few people (most of whom i bet are full of crap) saying they didn't do anything.
I am obviously not staff or an admin so if they want to dig more into this, they can... My answers just came from the last couple years of observations of people who did in fact cheat and just said they wouldn't do it again. Just passing along the info!
