Greetings.
My retail account was hacked today. I'm not even going to get into all the mayhem that was caused. Let me tell you it was extensive.
The point being...I froze my account with Blizz in February and haven't been back since. There was two months of time on account and some procedure I was to go through to unfreeze it. Whoever hacked it must have gone through this procedure and then proceeded to do what they did.
If you are like me, you used the same character names here as you did on blizz. Also, I rotated in and out the same types of passwords I use here. Since it's saved, I don't even know what the last password I used on Blizz was.
Something is going on. My email is not hacked. Just my blizz account. My PWs are not guessable and the only other game I play, is this one right here.
I am suggesting you likewise change all of your PWs at this time.
