There is such a gap between what the community expects out of AC vs what its actually capable of. I am not affiliated with AC in any way, but my understanding is that the methods for catching cheaters in TF2 are still in the stone age. VAC doesn't work, we don't play on any sort of client, server side AC solutions do almost nothing. There may be tools available to staff that are better than the eye test, but I doubt they're much better.
What do you guys actually want here? For staff to act immediately on every video compilation of STV demos? I am pretty convinced that these players are cheating, but how would you feel if community consensus was the bar for major bans? I feel like if they did that there would be equivalent backlash to what we're seeing now. Barring some massive improvement in anticheat tech, I just don't see this problem getting better and I do not think RGL is at fault.
We're just at a point in TF2's lifecycle that when you sign up to play a season of competitive TF2 you should know there's a 50% chance there's going to be cheaters, they're going to be fairly blatant but not blatant enough to be confidently banned, and that its going to take a small volunteer staff banging two rocks together quite some time to build a satisfactory case against them. That sucks.
