I have a free account in domaintools.com when I searched by Registrant I saw all domains registered for person name but all domain were something like this : s _ _ _ _ _ _ t.com p _ _ _ _ _ _ _ z.com why doesn't show me full letters?
This is not a domain privacy. Domain privacy does not show anything at all. If you know the name of the domain it displays it but you can't see anything about the owner. It will show you as protected. The trick here in this site is to get more clients that are free to paid membership. They have a paid membership in the site. So if you want to see all the names you have to pay. They only show you as a free member this way and if you would like to see exactly than you have to pay. But even if you pay you will not be again to see the domains owners details that have domain privacy. This is the trick here they make to attract more clients to earn money. A marketing strategy
