Your Google Account "[email protected]" has been disabled because you have entered a birthday indicating that you are not old enough to have a Google Account. In case you have incorrectly entered your birthday, we have a grace period during which you may confirm the correct date before the account is deleted.

Isn't this weird? An account that has been existing for over 10 years? How can this be?
