is private whois really private?

[domain]

I am about to launch a website but I want to stay completely out of sight. So I am thinking of private Whois. But is this really private? Or are there ways to find out that I am the holder? Your advise please. Thanks!

If you do a private domain name registration for your site.Really your information will be hidden from public view.If anyone do a whois lookup using the sites like WhoisXY.com they cannot able to trace the owner information.But they know the whois protection service provider like domainsbyproxy.Anyone wants your private information details they can contact domainsbyproxy and domainsbyproxy wont give the details without your authority.So privacy registration is useful.You can register domain name at 9cubehosting.com and get free whois privacy service.
