Facebook finally admits to tracking non-users

Would having manual DNS overrides in /etc/hosts prevent them? Eg:

  127.0.0.1  www.facebook.com
  127.0.0.1  facebook.com
  127.0.0.1  connect.facebook.net
  127.0.0.1  facebook.net
  127.0.0.1  ads.facebook.com
  127.0.0.1  ads.ak.facebook.com
  127.0.0.1  ads.ak.facebook.com
  127.0.0.1  creative.ak.facebook.com
  127.0.0.1  creative.ak.fbcdn.net #[textads]
  127.0.0.1  static.ak.fbcdn.net
  127.0.0.1  www.static.ak.fbcdn.net
  127.0.0.1  login.facebook.com
  127.0.0.1  www.login.facebook.com
  127.0.0.1  fbcdn.net
  127.0.0.1  www.fbcdn.net
  127.0.0.1  fbcdn.com
  127.0.0.1  www.fbcdn.com
  127.0.0.1  static.ak.connect.facebook.com
  127.0.0.1  www.static.ak.connect.facebook.com
