This sometimes happens if you link your email account to a youtube account. Anyway I believe that its something to do with youtube and not WD. Plus I can assure you that accounts before 2009 are a problem.

I have not tried it but you could change the email address of your youtube account to say a hotmail / gmx account and then log in. If it asks you to link accounts then reply no. It may work or maybe its too late after you have linked accounts.
