I used to work at chicago title, part of the job was running background checks on the ppl before we issued policy's. Everyone saying that they are safe from such things because they don't use social networking - think again. I could pull up way more information than I care to list here on any random amish dude who has never touched a PC in their lives. Birth records, property records, tax records, criminal records, credit records, job history, travel records, who your relatives are, this is all public information that anyone can obtain if they really want to - no SS needed either - all a SS would do is turn a 99.99% chance that your looking up the right person to 100%. If your seriously worried about privacy regarding anything posted on a site like facebook, wake up - there is a ton more information already out there that is way more private then anything you would post on such a site - and it's not going anywhere.
