Nexon does not do fraud, fraud is: 'In the broadest sense, a fraud is an intentional deception made for personal gain or to damage another individual.'
Nexon does not use the money for personal gain, it uses it to: Pay staff, run the severs, run Vivox, which have over 13 million users in games like Second Life, it to pay the company to use Hackshield on a international base, to control and fix server flow, their bills, etc.
NX users get ban as well, the idea that Nexon favor people with NX is false, Nexon ban people base on reports and addresses changes that the Hackshield detects. Unless you can FULLY prove that NX users are less prone to ban, then your infomation is wrong. I've seen people with NX get banned, we all do. Nothing more, the fact is your information is wrong and you're getting mad over nothing. You're trying to be smart but being smart takes a good set of information not raginging like a five years old.
