My first site, registered via a UK hosting company, displayed my name and address on whois which I was not especially pleased about. However I have opened a new domain through a US web hoster and not only is my address there but they have plastered my email address and telephone number for all to see.
Privacy is a pay for option which I did not take as I did not realise that the other items would be there too.
What do others do about this? I bought the domain for a personal website but you can imagine that if you put anything slightly controversial on the site - and I have items about falconry - then it lays you open to some deranged person with a dislike of falconers or whatever finding you very easily.
