A warning in my email

I just checked my junk inbox in my email and i recieved a email from "Blizzard Entertainment (WoWAccountAdmin@blizzard.com)" Saying that my account has been suspected of being sold or traded. I dont know why they think i am because im clearly not. The thing is it also says
"In order to keep this from occurring, you should immediately verify that you are the original owner of the account.

To verify your identity please visit the following webpage: http://www.worldofwarcraft.com/account/security/support "
When i click on it, it comes up with this site is blocked and is known as a fraud.
Please tell me if i am in danger of getting my account banned because it wont let me follow the link.
