Note that it is a requirement of domain name registration that contact information be present and be correct. You have to agree to that in order to own a name http://www.icann.org/en/resources/registrars/consensus-policies/wdrp/faqs http://www.icann.org/en/resources/registrars/consensus-polic... It isn't possible to tell the difference between the contact details being incorrect, and them being correct but the recipient choosing not to answer. But that is why the registrar gets to verify the details are indeed correct, and not the reporter. The registrars are allowed to take action to prevent spam and similar actions against usage of the contact information. So what should happen is that apparently uncontactable domain owners are reported, and the registrars catch the slimy peddlers.
