Scrape data by demographic

Hey,

I am looking to scrape some data based on a specific demographic in facebook, linkedin, college sites, etc...

Anyone have any tools that let you select demographics when data mining emails?

Or does anyone know of a tool that will search social networks for people with spacific demographics? Then I can just take those results into a custom scraper.

I have a working tool for facebook.Its coded in vb6.(100% my own code) I could give you some tips if you plan to code your own.

Hi Carnage - would you mind sharing with me also?
