What is blocking on Facebook and how do I block someone?

When you block someone they will no longer be able to do things such as tag you or see things you post on your timeline.
What happens when I block someone?
When you block someone, they won't be able to:
  • See things you post on your profile.
  • Tag you in posts, comments or photos.
  • Invite you to events or groups.
  • Start a conversation with you.
  • Add you as a friend.
If you block someone you're friends with, we'll unfriend you as well. If you don't want to unfriend someone but see less of their posts on Facebook, you can take a break from them.
When you block someone, you also won't be able to do things like start a conversation with them or add them as a friend. Keep in mind that blocking someone may not prevent all communications or interactions (example: in apps or groups) and only affects your interactions with that person on Facebook.
To block someone:
  1. Click in the top right of Facebook.
  2. Select Settings & Privacy, then click Settings.
  3. Click Blocking in the left side menu.
  4. In the Block users section, enter the name of the person you want to block and click Block.
  5. Select the specific person you want to block from the list that appears and click Block > Block [name].
Note: If you can't find someone using this method, try going to the person's profile and selecting Block from the menu in the bottom right of their cover photo.
Keep in mind:
  • When you unblock someone, you won't automatically be friends again. If you block a friend and then unblock them, you'll need to send them a new friend request.
  • People won't be notified when you block them.
