hacked account

[Akaasha]

Another way is that hackers will hack forums of various game sites and try the usernames and passwords they retrieve from them and then use those in selected MMO's in hopes they weren't smart and didn't use a different username/password for the game. A lot of people don't use various usernames and passwords, so it is very easy to get into some peoples accounts. They used this strategy in Diablo III, but I'm sure they use it for everything else too because it was very successful.

This. I bet this is the single most common way to loose your acocunt. I got my email breached once and they got hold of my Blizzard account and this was due to me using the same username and password everywhere. Lesson learned after that.

And I don't like people saying "hacked", that would imply someone singled you out and brute forced your account, that doesn't happen.
