It's not the first time that we have seen these "privacy statements" posted on Facebook status updates... and just like the last couple of times it made the rounds, it is still worthless.

Under Facebook's Terms of Agreement that you agree to when you sign-up, Facebook does not own your photos, videos, etc... BUT, when you created your Facebook profile you agreed to allow Facebook to use, distribute, or share your materials you post, depending on the privacy setting that you make manually inside your profile.

According to the myth busting site Snopes.com,

In any case, Facebook users cannot retroactively negate any of the privacy or copyright terms they agreed to when they signed up for their accounts, nor can they unilaterally alter or contradict any new privacy or copyright terms instituted by Facebook, simply by posting a contrary legal notice on their Facebook walls. Moreover, the fact that Facebook is now a publicly traded company (i.e., a company that has issued stocks which are traded on the open market) or an "open capital entity" has nothing to do with copyright protection or privacy rights. Any copyright or privacy agreements users of Facebook have entered into with that company prior to its becoming a publicly traded company or changing its policies remain in effect: they are neither diminished nor enhanced by Facebook's public status.

If you just cannot stand the idea of this the only ways you can make sure your material stays private, is to NOT sign up for a Facebook account, or delete the account you have.
