Haven't played a blizzard game in probably 4-5 years now. Last game I played was WoW and I dropped my subscription way back when.
No hacking while it was down, nothing like that. But they kept sending me emails to upgrade to battle net so I could choose whatever about it before it was too late.
So I went ahead and upgraded (not following links in emails just incase it was a phish). Within a week after doing so, my primary account, the one that had all the stuff on it, was hacked. So it had went years with no one logging in, and boom hacked as soon as I upgraded. I thought the timing of it was very questionable.
Did a scan on my system for trojans, keylogs, etc...found nothing. I still don't know how in the hell they knew my account had been updated and got to it within a week of it being done. Because according to the recovery rep, no one had been on my account for years and the first activity was the battle net stuff.
Now, I believe that some accounts are user fault, and hell even more than most may be user fault. It's just that the plainly obvious user fault is much easier to see than the other stuff going on, and having them just flat out say it's user fault no matter what is really questionable.
I still think they had someone pulling accounts at opportune times, or at points when some process is taking place they may not have secured like the battlenet account upgrade and linking everything to one account.
That no activity, upgrade to bnet and then breached in less than a week is just TOO convenient. Either they are getting logins or email addresses to use to brute force it, or something else is going on....the timing is just highly highly suspicious.
