PSA: GMs are banning players for attendance.

the logic behind it is that the person who bought the nx is a lost customer for an actual cash sale.

they want people to buy nx with money, not mesos.

But someone needs to buy nx for there to be nx to buy with mesos. Some people will buy nx for easy mesos, many people certainly. The less people buy nx, the more expensive it will be in mesos and the more it will motivate people to buy nx from nexon for profit.

Your logic is flawed, if they would lose money, there would've never been mts or tradeable nx items.

Edit:

Ninjad. Yep, it's for legal reasons. They're basically telling that when you buy nx with mesos or sell it you're doing it on your own risk and you have been warned.
