Privacy on social networking sites has been raised, such as facebook, announcing that new members will have their information accessible and also their pic accessible to other members. But this will just drive away most new users however big the network maybe. What one must do is read all the privacy and security agreements before registering and make sure what information they provide and change any relevant settings.

Orkut has had their own privacy setting for a while now, but before this was no possible either. Many people also use pictures from profiles to make fake profiles, so its something to be aware of, and be reported if found!

On complaint sites its always a case of people reporting fake profiles, but then its those people are the ones to blame to make their private information available to the world to see. So if you do use social networking sites not only read the privacy policy but also take care of your profile yourself from the settings and account information.
