Unfortunately I don't have the time to follow someone around and gather footage. Now that he is on notice I'm very sure that he won't do anything suspicious like this in the near future. You already have the footage, you know what his gameplay is like. I have footage too, but nothing convincing enough to say it's a bot. Yes he snaps to targets but this can just be written off as skill, even though in my opinion it isn't. I knew I needed to gather something that couldn't be written off as skill or luck. If he saw him before the smoke, ok sure it was skill. If he was spraying in the area, ok that was lucky. But he snaps without ever seeing a target and shoots him right in the head. That's an aimbot.
When you find something like this it should be beyond doubt proof of a bot. I have snapped to targets, I'm aware of that possibility as a legitimate player. But I have never in my 1600 hours snapped to a player and headshotted through smoke. And you can watch some of my clips.. most are unlisted, but I've pulled some pretty crazy shots. Always on people you can clearly see, regardless of your settings.
Ultimately I really don't care if you ban him or not. I'm not trying to convince you that he is, I'm telling you that he is. I barely play this server, and I barely know that guy. I am experienced in the game, and have caught my share of botters, and am telling you that shot isn't possible legitimately. You know that shot isn't possible legitimately, but your friendship has you in denial. I'm trying to help you guys out by giving you clear evidence that the game breaking, rage quit inducing, 50-1 attack chopper dude isn't legit. The server will be better off without him, and while someone shouldn't be banned for skill alone, in my opinion you finally have the evidence you were looking for to get rid of this guy and make 98% of the server happier for it. There's a reason several of you have hours of footage. You all had that gut feeling he was, maybe just never got as lucky as I did with the timing.
