Is there any way to do hide your identity on co.uk? I'm from the US and apparently anything that's country related, you csn't privately register. I had some good porn names for UK domain that weren't available elsewhere but no money in the world is going to get me to have a public record of me being associated with it.
That depends on the registrar of your domain some provide whois privacy feature for free, some for a fee, check you domain registrars site (I think you can add privacy feature even if you didn't purchased privacy at the time of registration)
If your first registration was a public name, then it's already in the whois record. And somebody can query that from domaintools or other similiar sites.
