"I tried to create a method of discovering who is behind fraudulent web sites, but was unable to locate domain registration’s raw data to make this viable. You must be able to search every domain registration that uses the same phone number or same address or e-mail address in the domain registration. The consistent and structured data provided by WhoisXML API made it possible to perform such searches. Finally, I managed to group and identify suspected fraudulent web sites. "
