may be blowing things out of proportion, but this is my story.
I have been a Combat Arms hacker for not too long (maybe two months or so), in comparison to the length of time that I've been playing in total (approximately one year). I usually don't update my hacks until a week after they've been patched, and so far, I haven't done much more than leech. Nonetheless, I tried using various hacks today after yesterday's patch. All attempts failed, as I disconnected before even reaching the log-in screen. After several tries, I gave up and tried to log on to the game normally. Instead, a message appeared saying I'd been banned from the game. I've never used any hacks other than chams, no spread, no fog, and no sway, so it would have been impossible to tell that I'd been using them from a 3rd person view.
I suspect Nexon may have implemented some sort of auto-banning system if a hacking tool was detected upon attempted log-in. It's just a theory, but from my point of view, it seems to make sense. Until new hacks are proven to work, I advise all of you to simply be careful of what tools you use, and how you use them.
