Questions regarding meso buyers

Hackers don't have to waste any of that meso to buy armor/weapons/pots and are making pure profit at a much higher rate than many players combined can achive through legit means, plus the fact that they advertise their site daily i'm shocked that nexon does not take legal action against these places, i would certainly hope they did already because they only stand to lose much of their income if they add the NX for mesos trade rooms.

Then people just flock to these meso selling websites and can get gross ammounts of mesos to buy cheap NX with, much cheaper than if they bought from nexon at least.
