Hiding WHOIS data is available for many domain zones. In international domains they can be hidden by support request; in most Ukrainian domains they are simply hidden by default.
That is why after registration of PP.UA domain so many people apply to the registrar to hide the data in their free domain as well. Unfortunately, hiding data in PP.UA domain zone is not available.
You can find this out even before activation of the domain, because to activate it you will need to agree to the rules of the domain and the agreement on the provision of contact data.
It is in this agreement you will find a section:
- All data provided by the registrant are publicly available and published in the WHOIS database, which can be viewed on the site dig.ua or via WHOIS protocol.
No registrar will not be able to hide the data in PP.UA domains. Also, note that writing something like "Private Person" or "Iam Batman" as full name will not work, since the main requirement of the domain zone — put a real data.
All these restrictions are primarily aimed at ensuring that free domains were registered and used by real people for legitimate activities and to prevent the use of domains by scammers.
