The message claims to put copyright protections on a user’s posts after they share the status update.
It typically reads:
“In response to the new Facebook guidelines, I hereby declare that my copyright is attached to all of my personal details, illustrations, comics, paintings, professional 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!”
The hoax doesn’t even have its facts right. A quick Google search will also show that there’s is no such thing as the Berner Convention. (Whoever originated it probably meant to write the Berne convention, which is an international agreement protecting literary and artistic works).
