Who they are: Pipl employs a novel business model to make money off of your information.

Unlike most data aggregators, Pipl doesn't collect or sell your information itself. Instead, the site crawls the Web looking for other websites and data miners with your name and personal data. It displays links to that information on a single page and sells targeted ads based on that information.

What they know: Like any other search engine, Pipl doesn't really "know" anything about you. It just delivers results about you based on what other sites know about you, and it links to those sites.

Those sites include BeenVerified.com, Intellius, Spokeo, PeopleFinders, PhoneNumber.com, ZoomInfo.com, Facebook, MySpace, Amazon.com, Picasa, and Flickr, among many others. It also will return any websites that can be traced back to you, including blogs, articles and government or public records.

How to opt out: You can't -- you have to opt out of all those other sites.
