How do I block someone?
To block someone:
  1. Click at the top right of any Facebook page.
  2. Click How do I stop someone from bothering me?
  3. Enter the name or email address of the person you want to block and click Block.
  4. If you entered a name, select the specific person you want to block from the list that appears.
People will not be notified when you block them.
If you can't find someone using this method, try going to the person's profile and selecting Block from the menu on their cover photo.
