This is what I wrote and posted on my FB page:

**ATTENTION ALL** Look closely at your Timelines!
A potentially serious privacy breech has been discovered. From 2011 back, there is a box at the top of the 'year' called 'Friends 2011' or whatever the year happens to be. It displays posts your friends have made to you...but some people have been finding Private Message posts among the wall posts here, myself included! PLEASE double check your timelines for past years and make sure this is not happening to you! Private messages should be just that - Private!
I learned of this from a friend on a forum, and checked my own page. This is real! So share it around and spread the word!!

Do the same! We need to make people aware of this...and have more proof for the stupid admins to get it fixed.
