You can rest easy about your Facebook profile: there is no charge of $5.99 to keep it private.
Much like similar posts that appeared in December 2009 and January of this year, they are fake.
The 2009 post ended up linking users to putting malware on their computer, so safe bet is to steer clear of this hoax.
Facebook has always stated it would never charge users for its basic services.
Do you know people that believed this recent Facebook hoax? Did you think it was real this time?
