I signed up for world of warcraft like a year ago and I played it for 15 minutes and I was all "well this is shit" and went and played fallout new vegas instead. today I got an email, the gist of which was "Due to suspicious activity, the Battle.net account myaddress@gmail.com has been locked. To restore access to this account, please follow these steps:". Does this mean someone bruteforced my account, or is this some blizzard idiosyncrasy that everyone is used to? I guess what I'm asking is should I give a shit?
