Important Information Regarding Nexon Guard in Maple...

Exactly what shouri said. If the GMs were actually active (lol, nice joke there), when the reports came in, they could investigate while it was going on. They could immediately determine if someone was cheating, rather than just banning them, and hoping that they were. There's false positives on everything, all the time. Going purely based on some trigger getting set to true is foolish, and only going to lead to issues. Even if they weren't hacking then, repeat offenders of this could be put on a "watch" list, where the GMs randomly check up on them, and then re-evaluate their situation. Since shutting off this new protection is significantly easier than working through/around it, it would be a useful tool to catch hackers.

But the point is that GMs aren't active. If the program catches what it believes to be a hacker, it should obviously DC them, thus preventing them from continuing to hack. This, of course, assumes that the guard can actually accurately identify hacking situations, which it probably can't.
