GM hacked?

And then there's the fact that, if Nexon were to start doing this sort of thing, there would be people who would go out, make a new account, go to a new IP, transfer the stuff, and then report it as a hack.

It's not really something easily trackable.

Sorry, I thought it was clear. It is easily trackable because I highly doubt the people mass-attacking accounts were changing IPs each time the logged onto an account. Look at all of the reports of being hacked, look at who accessed their accounts, look for similar IP accesses between them, track IP and report them to the proper authorities, reimburse account owner.

This would ensure that only people who were effected by the massive attack were dealt with. Some people would be missed, of course, but it's still a better plan of action than what they're currently doing which is nothing.
