If you've ever considered dropping out of sight or want to make yourself safer from someone who might want your personal information, you should pick up How to Disappear: Erase Your Digital Footprint, Leave Fake Trails, and Vanish Without a Trace by Frank Ahearn and Eileen Horan.
The first thing this book recommends is that you get out of Facebook, Myspace, and any other social website. Then the author tells you how to delete your name from some of the primary places a skip tracer will look for your information. He tells you how to alter some of the information you have in other places, so that you become technically invisible.
This book made me a little paranoid about how many or what type of people might be looking for my information. You will also discover a way to find out who is doing an online search for your name.
