Cataclysm Beta?

Hi,

I logged into battle.net to change some RealID settings, I found something weird with my account.

I see the following under accounts:

Q u o t e:
World of Warcraft: Wrath of the Lich King
[WOWNAMEHERE]
Americas & Oceania (US)

Then I see this, which is OK since I signed up for the PTR:

Q u o t e:
World of Warcraft: Wrath of the Lich King
[WOW1]
Public Test Realm (PTR)

But then, I see a new, third account listed... One that I never made... But it says Cataclysm Beta!

Q u o t e:
World of Warcraft: Cataclysm Beta
[WOW2]
Public Test Realm (PTR)

So, obviously, I went to my registered e-mail and I looked at what little official Blizzard e-mail I have and I don't have an e-mail.

So I'm wondering about this account, if I really did magically become a part of the Beta without an e-mail or if my account has been compromised (I have an authenticator).

The account I'm posting on is the "affected" account.
