Just to recap most of what has already been stated above.
1) If WE ever message you ingame, there will be a blue Blizzard logo by our name - period. No logo, please use report spam immediately.
2) Hyphens do not function the same way in a domain name (URL) as a dot. A string of Blizzard-ish sounding buzzwords strung together by hyphens does not a Blizzard domain make :)
3) NEVER go to a site like that. They are usually lousy with malware. If you DID visit the site, I'd recommend an immediate full scan of your system and changing of your password once you are certain you are secure.
4) When we have cause to action an account, we do it. We don't threaten, we don't give you any 'or else's', we'll take the actions we feel are necessary then contact you.
5) Last but not least, adding an authenticator to your account can be an extra line of defense if one of these or a phish ever slips past your radar.
