Restrict Friends On Facebook
When you add a friend to your Restricted List, they will not see any of your future posts unless they are tagged in the posts or the posts have a "Public" personal privacy setting.
Here's how to include users to your Restricted List in the Facebook mobile application. Keep in mind: These screenshots were recorded in the Facebook app on iOS.
Action 1: Go the profile of the user you want to include to your Restricted List. You can arrive by browsing for the user by hand, or by tapping on their name on a post or remark they have actually shared.
Action 2: Tap the "Pals" button under the user's name.
Action3: Tap "Edit Friend Notes."
Action 4: Scroll to the bottom of the list, and tap "Limited" to add a check mark to this row.
