GM owns a player

Of course, this is all moot if the account was never compromised in the first place, as the GM said. But that begs the question of how, exactly, the GM knows that the account was never stolen. It bothers me that fewer people on nexon's forums asked about that, and that the GM didn't go into any detail on the subject. IP logging, perhaps?

GMs almost assuredly use IP logging as a tool to catch hackers and abusers. Otherwise, everyone would just get "hacked", trade all their equips to a mule account, then submit a ticket decrying "oh noes, I got hekked!!!help me nexon and give me free stuff"
