How do you unblock someone on facebook? - Facebook Social Network

There are three ways to block someone:

1. Go to the Block Lists from your Privacy Settings page. Enter the name or email address of the person you want to block in the appropriate field and click "Block."
2. If you cannot find someone using the Person search field, try going to their profile page. You can block them by navigating to the "Report/Block this Person" link at the bottom of their profile page. Once you click this link, check the "Block this person" box and then click "Submit."
3. Lastly, please note that you can block someone through the "Report" link located next to messages in your Inbox.

People will not be notified when you block them. If you are unable to block someone using any of the methods listed above, it is possible that they have left Facebook or have restricted their privacy settings.

If you cannot block someone and would like to prevent them from viewing your profile, you can adjust your privacy settings accordingly. For more information on editing your Privacy Settings, click here. /help/?faq=12252
