Need to get every bit of personal information off of this website NOW

I want every single piece of information about me on this site removed. Any information on here can potentially harm my employment prospects in the next few months and this is a serious problem. My profile is **private** on any social networking sites I am a member of however some information still appears. Please advise. I went through and flagged and voted off a few things but some information still appears. What do I do? Mainly, I want to get rid of any pictures that appear, any links to social networking sites (linkedin and myspace appear on there), and any friends or related people.

Also, my name does not appear on Spock when I search myself on google but I appear as someone else's friend and that allows google users to click to my information. It's unreasonable to expect us to contact every one of our friends to ensure their social networking accounts are private!! Please help me clear up all of my information!!
