@ b

Your post is long and pointless tbh. You complain that you were emailed 3 times and was banned before you could even read them. Imo thats excellent service. You were obviously hacked and your toons used for the hackers own purposes. They contacted you THREE times as soon as they could, and without any response they then quite rightly banned your account to prevent further actions by the hackers.
As to your questions to Blizzard 'How did they get my password' - well tbh it was 99% YOUR fault about that, not Blizzards. "How did they pay" - is financial data, without you establishing your credentials - they are obliged to NOT reveal any data like that. And what IP address? Well since you can mask your IP (something i imagine every hacker would do automatically) seems really pointless.
Considering the above points - and the rest of your rant, I think Blizzard behaved exactly as they should - responding quickly and when there was no immediate response closing the account to prevent damage. You didnt secure your account with an authenticator - instead your post indicates you thought you were safe as 'linux doesn't provide a very hospitable environment to keyloggers'. You have not said how you contacted them and provided information to establish your ID, so I doubt Blizzard would answer any email - esp if it was worded like your post was. Have you even TRIED to contact them and follow the procedure? (Something literally thousands have done sucessfully.) If you cannot be bothered to secure your account (you obviously didnt think it was worth the cost of an authenticator), nor follow set procedures- then please enjoy RoM and other games, and leave your QQ posts with their blogs/forums.
