You can remove yourself by first searching for yourself on their site. It will most likely show the number of people in each state with that name (depending on your name commonality). Click on your state, then refresh the page. If you find yourself here, click on the right person, and again refresh the page. Gawk at the insane amount of info they have on you. Copy the URL, then click on "privacy" at the bottom of the page. It requires an email address to remove, and you can only remove two people per email address per day (wtf?)
I already removed my husband, my mom, my step-dad and my great grandma. Tomorrow on the list is my aunt and uncle, my cousin, and my grandfather.
