VAC has taken strong punishments to cheaters, banning keys for 5years rather than 6months. This has made the cheating population smaller, but stronger. For now the cheats are more private leaving VAC with the position to detect the cheats without knowing how they work. I would have to say, if you cheat and aren't inside the cheat network(and I mean deep in). Stop now, because even OGLs like RageOGL which hasn't been detected in over a year are now detected and have to be changed.
