I have my Battlenet account on its own email address for a while now. and no other service uses it. Please can someone advise if this is legit, or what it means please. This would be appriciated.

Before the usual questions, I have no keyloggers on my computer, my account has never been hacked, I follow very strict practice on the web and only download applications from trusted sources when needed. I scan my computer daily, with a major scan every week, and i have not had a virus on this computer for about 3 years. The last time was due to a dodgy cookie.
