Servers got hacked in august, but they didn't take any personal info.
@OP: Have you used the same email that you use for world of warcraft on another website? Have you used a similar password somewhere?
You might think that it's safe and those websites are keeping your data safe. However, that's not really true: they sell that data out for extra money.
Yes, I have used that email for a few different sites but only reputable ones. I think pandora, wow, imgur. Maybe a couple more like that. They might sell my email sure but passwords?
I heard about the october hack (or whenever it was) but I would imagine that was too long ago, i.e. they wouldn't have waited 2+ months to hack me after that, I wouldn't think. I can understand them getting my email, I just don't know how they would get my password.
