that means ow is working
it's designed to not waste your time by giving you borderline or non-cheaters
it's supposed to ban obvious cheaters, because those are what ruin games
Cheating usually comes in waves, a cheat gets released valve will leave it for a while so they can ban the largest number of people, this used to matter because before you had to pay for the game but I guess it still kind of matters because you have to reach level 21 to get prime or whatever and so it goes down after the ban then someone makes a new cheat and it slowly goes back up and then valve waits and so on.
Valve anti-cheat apparently also learns what to look for when it's trying to catch cheaters so you are more likely to get more accurate cases and given the new low trust factor system a lot of hackers are likely to go against other hackers.
It's becoming harder and harder to ban cheaters. If Valve bans someone that wasn't actually cheating, they can sue the company and it's pretty bad.
I think they're trying to only ban blatant cheaters.
With the last updates, Valve is trying to be more agressive with third-party softwares, I think it can work, because it doesn't try to ban cheaters, they just put them in "Low trust servers", that way they can't be sued and we're apart from them
The actual problem is that the game isn't split between prime and non prime. If you have a friend you queue with and he has prime, you can play actually. This is the new boost method, a high ranked player queue with a non prime cheater which boost. Its 50% 50% at this point. If you dont do it obvious with the cheat , you can get away with it.
If you get low trust factor in MM u're fucked
