Large amounts of personal data are collected by data brokers like Intelius, Spokeo and Whitepages - which makes this easier to pull off. It's fairly trivial to find answers to questions like "What's your DOB?" or "What's your billing address" by looking in one of these places. Most data brokers will have opt-out pages where you can request removal of your data - though they don't make it easy. There are also services that help with this: MyPrivacy (reputation.com/myprivacy) which I work on and Safe Shepherd (safesheperd.com).
