People being hacked since the last Server Check.

So like having a 64 character password and a 16 character PIC?

And never sharing it, never writing it down, never sending it across WiFi without at least a VPN encrypting it, never sending it across an open network... using a virtual machine that's a read only image so everything in it gets reset every time you log in (no possibility of persistent keylogging or spyware)...

That would be very near the limit of what you could to do protect it.
And even then you'd be susceptible to a few things, mostly on Nexon's side.
