Did your ban look like that as well? I'm just curious as to why mine's for harassment instead of "illegal use of third party programs".
And if you're wondering what the message for the actual dupers' banned accounts looks like; here:
i.e. No chance of getting unbanned, unlike the first message.
EDIT: And yeah, read my post a 7 posts down. Nexon's done a pretty good job in my opinion.
~18 hour maintenance and many hours wasted from the rollback because of this exploit. I guess hackers truly do have a negative effect on the game.
