Your reaction is what makes it worth it to them. Why waste anger on such a non issue. Just leave the server, problem solved. What boggles my mind is that after it becomes obvius that a cheater is on the server, people stay on it. For what? If people just ignored them and left when they are spotted. It wouldnt be so much fun would it.
Guys like Optical often google their handles, just to see what peoples writes about them. Just look at youtube, the poor sap has a profile that has no other reason than to troll with and attract angry comments.
It is obvious that Crytek is either unable, or unwilling to properly deal with the cheating situation, but you can destroy trolls easily. Dont feed them.
