A Facebook hoax that claims that posting a legal notice on your Facebook wall will protect your copyright and privacy rights from Facebook itself has surfaced yet again. Here are the facts: when you agree to Facebook's terms of use you provide Facebook a non-exclusive, transferable, royalty-free, worldwide license to use any content you post. You do not need to make any declarations about copyright issues since the law already protects your ownership of the materials, but grants Facebook the right to use them. Any privacy declaration is worthless and does not mean anything. Want to read the terms for yourself? Look at this section of the Facebook site where you grant Facebook permission to use, distribute, and share the things you post, subject to the terms and applicable privacy settings.
