recently purchased a copy of Call of Duty Modern Warfare 2. After playing for a few days the number of hackers I have encountered was ridiculous. I'd say the number of hackers is increasing every day. I read the VAC bans hackers the same way Blizzard has been doing it for wow. They ban as a large group not per infraction. After the first two wave I think we will be able to see if it works effectively for this type of game. COD MW2 PC Cheat / Hack Free Games: The biggest benefit of using IWnet by far is the fact that you dont have to worry about joining a server full of aim-bots, wallhacks, or cheaters. Or relying on the server admin of the server to constantly be monitoring, banning, and policing it. Modern Warfare 2 on PC allows us to control the quality of the game much more than ever before as well as utilizing the VAC (Valve-Anti-Cheat) system to keep games clean of hackers and cheaters.
