You can't be mad at Nexon for doing their job. Afterall if they didn't even try they would lose a majority of the NX buying players and then we would not even have a game to hack.
It's a never ending war between game developers and game hackers. We dropped our 2000lb bunker busters for months and had our fun.. Now they are sending in the drones and attacking back... It's not the end of hacking, just a new battle in the endless war.
