Whois info can and does easily get falsified. So the basis of his entire research which was built on checking whois is incorrect. In other words there is nothing preventing anyone from registering a domain name using someone elses contact info. Which is actually done quite frequently by web designers as only one example on behalf of their customers for legitimate reasons. Separately, this is also incorrect: "and it’s the administrative contact, which means he owns the domain" The "registrant" actually owns the domain. Not the admin contact. Of course the admin contact can own the domain. And all the info can be false anyway as mentioned. For example in the case of the domain "ycombinator.com" the admin contact is "Kirsty Nathoo" who, according to linkedin, is the "VP Finance and Operations at Y Combinator". The registrant is Ycombinator LLC and of course that makes sense that they are the owner. Geo locating ip addresses also produces far from gold standard results.
