When you add a friend to your limited profile list on Facebook, he becomes unable to see content you've restricted from members of the list. The privacy settings Facebook rolled out in August 2011 restrict all content you post from members of the limited profile list.
We had a look at how to create and manage such a list so that you can stay Facebook friends with someone without letting them see every single little activity you get up to. Head to the Facebook profile page of the person you want to add to your restricted list.Click on the Friends drop-down box that appears at the bottom right of their cover photo. Select the option Add to another list..ow, click on the Restricted setting that appears on the next menu. This should enbolden the text and put a check mark next to it. Now, when you next post content, you can decided whether you want it to be public content or just for the eyes of your Facebook friends.
