Just for the record, our Anti-Cheat team does not have a magical bot or algorithm that tells us if a player is cheating or not (that would be cool though, better VAC detection when Valve?). We look at each reported case individually, which of course means that we do analyse the provided demos and look at any other evidence that is relevant to the case. We don’t share any information about proper ban proceedings or specific case info with the public simply because we cannot alert suspects that they are under review or risk giving cheaters the chance to adapt to our methods. We don’t ban players “on a whim”. No case result is decided on by a single person, it is a collective task of ETF2L’s Anti-Cheat staff.
I don’t know why you are so fixated on what happened like nine years ago, admittedly I haven’t been on the staff for too long but I can still tell you that things have very much changed and improved over that time period. You can’t handpick two single incidents that old and apply them to the current day, especially when the staff-member composition has changed multiple times over the years.
Your point of “they didn’t properly watch the demos because the other team didn’t get a warning for having two Pyros on Gully last!”, well… frankly it’s not our task to provide warnings for that and afaik your team didn’t report the incident to ETF2L’s League Staff either. Your team still easily won that round and the two Pyros had no effect on the outcome of what was essentially a 7-minute Gullywash 5-0 roll, there is no reason to forward the incident to League Admins if your own team doesn't care enough to report it either.
I also don’t know why you go around spreading a rumour that the single reason you got banned was one clip. That is pretty hilarious to be honest. Don't think about saying you don't mean it like that either, we had people approach us asking if the reason for your ban was that single clip.
PS: Your argument of “proving everyone wrong at i65”; even if you do attend LAN and do well there, that does not automatically mean that you have never cheated in the past.
