I tried Googling it, but I couldn't find an answer.
I would like private whois, meaning I wouldn't want to display my home address etc.
However, I still would want to list email-address.
Under ICANN's policy for domain names, they all must list the owner of the domain names:
However, some websites (such as GoDaddy and Name.com) are able to use their information instead for about $10/yr. The problem with the email address that usually use is it is a forwarded email address. For example: A WHOIS will list email@example.com but emails that are sent to it are redirected to firstname.lastname@example.org (some registrars also have spam filters that emails must go through first in order to be redirected). To be honest, I wouldn't worry about having your own information in the domain WHOIS because you have to remember the millions (if not billions) of people that have listed their information as well.
