Phone numbers and addresses are fast becoming like email addresses. In the same way that you can assume putting your email address into any website form that requests it will eventually result in spam, putting your phone number into any phone or your address into the database of any service provider will eventually result in a "leak".

We are to the point that to maintain any semblance of privacy, you need at least two email accounts (one you don't mind getting spammed), two phone numbers (one you don't care about facebook and others tracking) and two addresses (a mailing address/box service and your actual physical address).
