Facebook offers a great -- and free -- way to connect with friends and family, but if you are not careful about your security settings, your site activity can be published for anyone to view. Comments you leave on other posts, for example, are displayed and made available for liking and commenting by other users as well. With user blocking enabled, you can unfriend specific users and hide your comments from their view plus prohibit the user from communicating directly with you on Facebook. Other privacy settings allow you adjust the overall audience of your posts and shared items.

Click the "Privacy Shortcuts" icon, resembling a padlock with three horizontal lines, at the top right of any Facebook page. Select "How do I stop someone from bothering me?"

Step 2

Step 3

Tips

  • The other user will not be notified when you block him.

  • If you are unable to find a user by searching in the "Privacy Shortcuts," navigate to the user’s timeline, select the gear icon to the left of his name and choose "Report/Block This Person" from the drop-down menu. If you are still unable to locate the user's page, he may no longer use Facebook or have restricted his privacy settings.

  • When you select "Limit Old Posts," any content you have shared with "Friends of Friends" or "Public" will be changed to a "Friends" audience.

  • A post with a "Public" audience will be visible to anyone on the Internet. A "Friends of Friends" audience includes your friends as well as the friends of your friends. This option is also the maximum audience option available to minors posting on Facebook. A "Friends" audience displays posts only to your Facebook friends -- and will expand to include additional non-friend users who are also tagged within the post. A post with an "Only Me" audience is visible only to you -- though it will expand to include additional users who are also tagged within the post. A "Custom" audience can be configured to include or block specific users.
