This hoax is doing the rounds on Facebook
The claim that Facebook will charge you to keep posts private
The hoax instructs you to copy and past the following text and post it on Facebook
"Now it’s official! It has been published in the media. Facebook has just released the entry price: £5.99 ($9.10) to keep the subscription of your status to be set to “private.” If you paste this message on your page, it will be offered free (I said paste not share) if not tomorrow, all your posts can become public. Even the messages that have been deleted or the photos not allowed. After all, it does not cost anything for a simple copy and paste."
