I have been playing CS since 1.6. I know a cheater when I see one and I know wallbangs can happen. You mean the guy with 100% headshot rate, shoots exclusively at people thorough walls before seeing them, and puts their face into a wall to stare at the enemy and track them walking through the map on 1v1 is playing legitimately? Unless I’ve done something to tank my trust factor and it hasn’t changed in something like 5 years, then there’s no reason for me to have low trust factor.
The cheater problem was not like this before and has been getting steadily worse. Just because you don’t see them doesn’t mean they don’t exist. Besides that wallbangs are nothing like in 1.6.
