Hi Stab,
I can confirm you are restricted on all 4 realms. Looks like at the time the restriction was put in place it was for the full 14 days, which usually means a CD-key problem. One bad attempt at entering the key won't cause that, but repeated attempts at using a valid key, but entering it incorrectly can. The security sees it as an attempt to find a valid key.
Any attempt at trying to use a hacked/generated/invalid key will cause the same restriction. You will need to wait the restriction out at this point as it cannot be lifted.
If you would like to verify your CD-keys validity you can email support@blizzard.com and provide it in the body of the email.
