You can limit what individuals can publish on your profile by using the Restrict Accounts option. — Users can choose whether or not others can view comments on their posts, and their chat will be redirected to your Message requests, so they won’t see it when you read it. — Restricted accounts can’t see when you’re online or whether or not you’ve read their messages. — Only that person will be able to see new comments from restricted accounts on your posts, and you can choose to see them by tapping See Comment. You can choose to allow others to view their comment by tapping Approve, then Approve again to confirm, or you can delete or ignore it. For those you’re following, there’s also a mute option. Tap Following, then Mute from their profile to stop their posts or stories (or both) from appearing in your various feeds. This is ideal for someone who shares more stuff than you can keep up with but with whom you don’t want to disconnect.
