Excerpt of the response I got: "Please note that Protected Domain Services is not the
registrant, owner, hosting provider or registrar of this domain.

We have reached out to the registrant ( or legal owner) of this
domain. The registrant has claimed that all unsubscribe attempts made
in the past have been adhered to. Furthermore, it is our understanding
that the Registrant has agreed to cease this type of behavior moving
forward. As we are not the hosting provider, it is difficult for us to
verify the domain's behavior or compliance. As such, we would ask that
you please let us know if this problem persists moving forward. If so,
we would be happy to investigate further."
