Actually your phone numbers, address, name are all accessible on the internet - regardless if they are 'unlisted' with the phone company. Do you own a home? well the local tax organization makes the tax information on the property public information - that includes your name / address and phone if it is on your account. Also various member lists become public info and searchable such as school, volunteer, church, interst groups, etc.... Just try it - search your own phone number, or your address, name, etc., it will shock you whats out there. And if LE is involved - gaurantee they get whatever phone numbers called a certain number very easially.
