That works for the mil and edu domains, because there is a verification process creating a barrier to entry, and therefore some measure of validity. There are so many new TLDs out there that I couldn't even pick out the real ones from fake ones if you gave me a list. And most of them require no verification whatsoever, so They're completely open to legitimate users and spammers alike.
