I am strict about not giving out personal data. I don't give anyone my home address unless I have to by law or there is damn good reason for that person to come to my house -- such as when I order out for pizza. My driver's license, auto registration, bank, health insurance, or other folks who have a legitimate need for a contact address all have mailing address which is different than where I physically live. I do receive mail at that address...it is a legitimate contact address. But it is not where I physically live.
