The difference between unfriending, blocking, and restricting someone

Facebook gives you three separate tools to control who sees your posts and who can contact you. Unfriending removes someone from your friends list entirely — they can no longer see posts you mark as "friends only," and you stop seeing their posts in your feed. They can still message you unless you block them, and they can still see your public posts and profile information you have set to public. Blocking is stronger: a blocked person cannot message you, see your profile, find you in search, or see anything you post, even public posts. Restricting is lighter — a restricted person stays on your friends list but cannot see posts you mark as "friends only," though they can still message you and see your public content.

Most people unfriend when they want distance but not confrontation. You block when someone is harassing you or you want a complete wall between your accounts. You restrict when you want to keep someone as a friend for practical reasons — a coworker, a distant relative — but do not want them seeing your personal posts.

Key Takeaways

  • Unfriending removes someone from your friends list but does not prevent them from messaging you or seeing your public posts.
  • Blocking prevents someone from messaging you, finding your profile, or seeing any of your posts, including public ones.
  • Restricting keeps someone as a friend but hides your "friends only" posts from them while allowing messages to continue.
  • Facebook does not notify the other person when you unfriend or restrict them, but they may notice on their own.
  • You can undo an unfriend or block by sending a new friend request, but the other person must accept it.

How to unfriend someone on Facebook

To unfriend someone, go to their profile by searching for their name or clicking their name in a post or comment. On their profile page, look for the "Friends" button (it appears as a blue button with a checkmark). Click it, and a dropdown menu appears with the option "Unfriend." Click "Unfriend" and confirm when Facebook asks if you are sure. The person is now removed from your friends list.

On mobile, the process is the same: find their profile, tap the "Friends" button, and select "Unfriend." If you cannot find the "Friends" button, scroll down on their profile — it may be below their cover photo or in a menu marked with three dots.

How to block someone on Facebook

Blocking is stronger than unfriending and takes a few more steps. Go to the person's profile, click the three-dot menu icon (usually in the top right of their profile), and select "Block." Facebook will ask you to confirm. Once you block someone, they cannot see your profile, message you, or find you in search results. They also cannot see any posts you make, even if they are set to public.

If you change your mind, you can unblock someone by going to Settings, clicking "Blocking" on the left side, finding the person's name in your blocked list, and clicking "Unblock." Unblocking does not automatically make you friends again — you would need to send a new friend request.

How to restrict someone without unfriending

Restricting is useful when you want to stay technically friends with someone but limit what they see. Go to their profile, click the three-dot menu, and select "Restrict." A restricted person will no longer see posts you mark as "friends only," but they can still see your public posts and send you messages. They will not be notified that you restricted them.

To unrestrict someone, go back to their profile, click the three-dot menu, and select "Unrestrict." This returns them to seeing all your posts that are visible to friends.

What the other person sees when you unfriend them

Facebook does not send a notification when you unfriend someone. However, the person may notice on their own — they might realize you are no longer on their friends list if they visit your profile, or they might notice they no longer see your posts in their feed. If they search for you, they will still find your profile and see any posts you have marked as public.

If you unfriend someone and then want to be friends again, you have to send a new friend request. The person must accept it. There is no way to "undo" an unfriend when ready — you cannot just click a button to restore the friendship.

How Facebook stores information about removed friends

When you unfriend someone, Facebook does not delete the messages you sent them or the comments you made on their posts. Those remain visible to both of you unless you delete them individually. The person can still see posts you made on their timeline or in comments, and they can still see any photos you tagged them in (unless you untag yourself).

If you want to remove a specific message or comment, you have to delete it yourself. Go to the message or comment, click the three-dot menu next to it, and select "Delete." This removes it from both your account and the other person's view. Blocking someone does prevent them from seeing new messages you send, but it does not erase old conversations — those remain in their message history unless they delete them.

Unfriending versus leaving a group or muting someone

If you want to stop seeing someone's posts without unfriending them, you can mute them instead. When you mute someone, their posts stop appearing in your feed, but you stay friends and they can still message you. To mute someone, go to their profile, click the three-dot menu, and select "Mute." You can mute someone for 30 days or indefinitely.

If you are in a group with someone and do not want to see their posts there, you can leave the group without unfriending them. You can also mute the group itself so notifications stop appearing. These options are useful when you want distance from someone's activity without the finality of unfriending.

Frequently Asked Questions

Will the person know I unfriended them?

Facebook does not send a notification, but they may notice if they visit your profile or look at their friends list. If they search for you and your profile is public, they can still find you and see your public posts.

Can I unfriend someone and then friend them again?

Yes, but you have to send a new friend request and they have to accept it. There is no when ready way to restore a friendship after unfriending.

What is the difference between blocking and unfriending?

Unfriending removes them from your friends list but they can still message you and see your public posts. Blocking prevents them from messaging you, finding your profile, or seeing any of your posts.

If I block someone, can they still see old messages between us?

Yes. Blocking stops new messages and hides your profile from them going forward, but old conversations remain in their message history unless they delete them.

Can I restrict someone instead of unfriending them?

Yes. Restricting hides your "friends only" posts from them while keeping you as friends. They can still message you and see your public content, and they will not be notified.
