It’s basically luck of the draw with trust factor and region
I regularly run into cheaters who I watch the demo afterwards and they just sit there aim locked onto someone and tracking them through the wall for 10s before blasting them without ever seeing them, or react to things they can’t see (e.g. suddenly flick to a corner someone is walking up to in a panic wo seeing or hearing a thing). Basically every other game has someone suspicious if not blatantly cheating from the start. If was bad in CSGO and it’s 10x worse in CS2
