Any recent hacked accounts from Southperry users?

I fully understand that it would be a huge mistake to immediately assume these guys are behind it all. It's not hard to post a list of 150+ random accouts stolen through conventional means such as social engineering. I'm pretty familiar with some of the cheap tricks that script kiddies and amateurs will use to make people believe they are capable of things they clearly aren't.

Nexon should know if that list is real or bogus. They just have to look at the first column of numbers to see if they are really the serial or account numbers as used in the data base. No random list from physhing or keylogging or whatever would produce a list of accounts in sequence, all created around the same time.
Some people have logged onto some of those accounts. They could tell the age of the accounts from the completion date of the maple island quests of the first character ( i think most do at least a few of those). If they were all from the same time, the list is probably a real database dump.
