Want to block somebody from seeing your Facebook profile? Or did you block somebody, then decide that you want them to be a part of your Facebook experience after all? Here’s how to block and unblock people on Facebook.
1. Login to your Facebook account.
2. Click the arrow in the upper-right corner of the screen, then select Privacy Settings.
3. At the bottom of the page, click the Manage Blocking link.
In the Block users area, type a Name or Email, then click Block to search. A list of names will appear where you can select Block.
If you want to unblock a person, the list of the people you have blocked will appear below the Name and Email fields. Simply click the Unblock link next to the name to let the person see your profile again, then click Confirm on the dialog that appears afterwards.
