I found this article on
The Wall Street Journal
Escaping the 'Scrapers'
http://blogs.wsj.com/digits/2010/10/11/escaping-the-scrapers/
The article details how you can remove yourself from many different sites that collect information about people. I hate the fact that companies or people collect information about you and profit from it.
If you read the article, you'll notice it'll take some time and effort to get yourself removed. If you have the time though, I think it's worth it.
