If you have no idea how to turn off comments on facebook post, you need to log in to your Facebook account first and create a new post. Next, before posting your story, change all the privacy settings. For that, go to the right side of “News Feed” and “Your Story,” where you will see a box with Public, click on it and choose More and then, choose “Public” if you want to make your posts visible to everyone and “Friends” if you make the post visible to your Friend list.
