A privacy notice is finding its way onto many Facebook profiles, as it supposedly offers protection from Facebook's claim to the copyright of users' individual posts. It's unofficial, doesn't actually do anything, and you should not post it if it crosses your path.
Here's what the fake notice looks line:
In response to the new Facebook guidelines I hereby declare that my copyright is attached to all of my personal details, illustrations, graphics, comics, paintings, photos and videos, etc. (as a result of the Berner Convention). For commercial use of the above my written consent is needed at all times!
(Anyone reading this can copy this text and paste it on their Facebook
Wall. This will place them under protection of copyright laws.) By the present communiqué, I notify Facebook that it is strictly forbidden to disclose, copy, distribute, disseminate, or take any other action against me on the basis of this profile and/or its contents. The aforementioned prohibited actions also apply to employees, students, agents and/or any staff under Facebook's direction or control. The content of this profile is private and confidential information. The violation of my privacy is punished by law (UCC 1 1-308-308 1-103 and the Rome Statute).
It goes on to warn that if you avoid publishing this statement you'll be giving Facebook the rights to your posts. In reality, you already did that when you agreed to the terms of service. Posting a notice like this doesn't change anything. If you don't want Facebook to own any content you create with the service, or at least the rights to use it, don't post it (or delete what you've already posted). This is a price you pay for using the service. Remember, if you're not paying for it, you're likely the product.
