There have been lots of posts in Facebook shared all over the place speaking to Post Privacy.
Here are an example of the post that is wandering around FB and is totally incorrect:
Borrowed this from someone*** may I request you to please do something for me: I want to stay PRIVATELY connected with you. However, with the recent changes in FB, the public can now see activities in any wall. This happens when our friend hits “like” or “comment”, automatically, their friends would see our posts too. Unfortunately, we cannot change this setting by ourselves because Facebook has configure
d it this way. So I need your help. Only you can do this for me.
PLEASE place your mouse over my name above (do not click), a window will appear, now move the mouse on “FRIENDS” (also without clicking), then down to “Settings”, click on “Settings” and a list will appear. REMOVE the CHECK on “COMMENTS & LIKE” by clicking on it. By doing this, my activity amongst my friends and my family will no longer become public. Many thanks! Paste this on your wall so your contacts will follow suit.
I used Facebook Help center to search for any relevance to this and found none. I did find an article that confirms this is incorrect – http://www.facebook.com/help/community/question/?id=2449187
You have complete control over your Post Privacy.
Look at the Privacy Setting button when you create a new post. It works and is all you need to pay attention to.
All of the posts that are floating around FB regarding asking your friends to control your privacy permissions are false.
