def activation_key_expired(self):
        """
        Determine whether this ``RegistrationProfile``'s activation
        key has expired, returning a boolean -- ``True`` if the key
        has expired.

        Key expiration is determined by a two-step process:

        1. If the user has already activated, ``self.activated`` will
           be ``True``. Re-activating is not permitted, and so this
           method returns ``True`` in this case.

        2. Otherwise, the date the user signed up is incremented by
           the number of days specified in the setting
           ``ACCOUNT_ACTIVATION_DAYS`` (which should be the number of
           days after signup during which a user is allowed to
           activate their account); if the result is less than or
           equal to the current date, the key has expired and this
           method returns ``True``.
