Are you legit?

It's a failure of game design when people can't tell who is hacking or what actions are having horrible effects on the economy. Basically every problem except duping has a relatively easy fix if Nexon got off their fat asses. And if those other problems were fixed, the potential damage from duping would be reduced too.

So the bottom line is, we shouldn't have to have this discussion. Defending a standard of legitimacy doesn't have much meaning when it's so easily breached due to Nexon's incompetence.
