What is the evidence base for catching a cheater (map hacker) in online play?

If the answer is something like "there is no 100% proof in online play," then explain: what are you happy about?
Not that there is a cheater, but that the system doesn't have a 100% indicator to detect them? - there's nothing to laugh about here, but rather to cry! Instead of putting effort into finding these tools, you boast about the impunity of this phenomenon, thereby shaping the minds of young players and making them believe that this method of play is acceptable.
