I didn't ban you. I've never played with you. You were detected doing things only a cheat program could do. You are really hung up on this "admins banned me" thing. Get it through your head. This was an automated system that monitors players and their actions. It doesn't record demos, it looks at players actions, positions, variables, angles, ping, packet loss, and a multitude of other things. It looks at all the NUMBERS and numbers don't lie.
You sound exactly like someone who resorts to cheating. You aren't good, so you get cheats, then when you're busted you double down on "I don't cheat I'm just that good" because instead of just practicing like a normal person you can't fathom a world where you are not instantly good at something. You cannot comprehend someone being better than you because you think you are God's gift to TF2. We see it all the time. Years of appeals where people just like you come in with the exact same attitude, and then a few years later come back and apologize saying we were right all along, and we always say the same thing. We. Don't. Unban. Cheaters.
You blatantly cheated, you got caught, grow up and move on. We are done with you.
