How does facebook know who my friends are on my yahoo messenger friends list?

In the People you may know section on facebook they are suggesting friends that I’ve never met in person who live in other states and have no mutual friends. How would facebook know that I know them?

  1. when you signed up, you probably added your email address, and there is a check box that asks if you would like to allow facebook to add your contacts from that email address. you probably didnt uncheck it.

    not 100% sure, but i think you can remove your email contacts from your facebook ones in the settings somewhere.
