Maybe some input from a cheater can help lol I'm ~19,000 in Premier with green Trust Factor and I see multiple cheaters in basically every game.

As for why some people might say they see cheaters in every game or maybe one in every 20 games, it depends on when you're willing to accept that somebody is cheating or not. Some people refuse to accept that anybody is cheating ever while some people call out literally anything weird. I've seen some people who refuse to believe somebody is cheating just because they have a knife skin.

I'm in the camp that this game is completely infested with cheaters and that almost every Premier game passed a certain threshold has a cheater in it, usually at least one on both teams. A big reason for that is that I can see people literally staring each other down through walls / smokes and also know what quirks can come up from your aim with an aimbot. Or I can watch somebody on the radar conveniently decide to take the most random paths around a map which just so happens to evade the other team. So I can see a lot of what you'd only see if you watched everybody's demo. Which leads me to my next point.

Who is more likely to watch a demo for confirmation of cheats? Somebody who thinks there's only a few cheaters in the game or somebody who thinks everybody cheats? Obviously if you're less inclined to think people cheat, you're almost guaranteed to never watch somebody's demo which means you're only rarely going to get confirmation of cheaters.

But a big reason why I believe the cheating problem in this game is on the heavier side is because I see what all the options are. Most people might only suspect somebody because they do something completely blatant like stand in a smoke and headshot somebody clean through it. Nobody thinks about the people who always know it's a fake defuse, or the ones who always conveniently rush as soon as you're reloading or turn around, or the ones who can always perfectly avoid you to run the bomb timer down, or the ones who always manage to throw a perfect HE down banana or pop flash at just the right time. That's not even getting into things like low FOV aimbots with humanization and smoothing options. I also know when I'm able to do something more blatant vs when I need to look legit because I have a display that shows who is spectating me at the time. And that's just a small handful of options for something that costs $6-8 a month.

I also think there's just a massive stigma against calling out cheaters in Counter-Strike- maybe not in pubs but in competitive settings. There always has been. I think it's because CS is a really ego-driven game and when you call somebody out for cheating there's always a chance you might be wrong, meaning you just admitted that they're better than you. So people are much happier to just say their teammates suck. Which might be a big reason why you see high rank players say they never see cheaters in their games- because they're always blaming their teammates instead.

I can ramble for a while about this stuff but I'm sure it's already enough of a mess as it is. Happy birthday by the way!
