The following link provides information on web-site owners. It provides private e-mails, addresses and names.  I've used it. It works!  Scroll to the bottom and use 'Domain' search.  If a scam artisit or street-sign spammer is using a sub domain it is not of much use...If they own the domain...it works!  Once the search is loaded, scroll to the bottom of that page and it will display the info.
