How many characters do you have? Level of each character?

Giving an IGN doesn't really have to do with anything...

You'd be surprised, in the current world as we know it, every single obtainable amount of collected information can be used to hack. If I were to hack a corporate router, just by 'finding' out some small tid-bits can give me the slightest lead. You might consider it as illogical or insignificant, but some others here in the forums might disagree. Sure, giving out an IGN, seems harmless. Then why don't we put this in a corporate-standpoint, if a personel or staff member had access to a certain computer, and I were to execute social-engineering on them, little-by-little, I can make an estimate as what their password and login could be.

EDIT: Back when I was in college with my best friend, I knew his favorite game, and one of the IGNs he'd register most games under, so one day.. I went on his PC and actually got access to it, since his password = his IGN for his games. I'm using this as an example though. Most situations wouldn't be this simple and easy.
