How to Restrict Someone From Seeing Your Posts on Facebook
We all have that one friend. You make a post about a certain subject, and here comes the narcissist to make their opinions known to all. You can unfollow them, but that doesn't stop them from seeing or commenting on your posts. Another option would be to add them to a Restricted List permanently or when you make a new post.
The Restricted List allows you to make posts to your friends, and anyone on that list won't see your posts. The only limitation is that any public posts, posts on a friend's timeline, or posts you are tagged in will be seen. In other words, restricted lists only work when you make a new post.
