Go ahead and use them, you're only risking your computer and your Nexon account(s).
None of them are real, if you find one, link it to me so I can hack it and disable it .
If they ask for your username and password, they just steal it and change your info.
I've hacked about 10+ meso,nx,xbox points, etc; generators and have a list of 1,000+ usernames and passwords.
But i'm a good guy and don't use them for bad reasons, I just disable keyloggers and phishers
