what happens when you block someone on facebook

When you block someone on Facebook, that person will not be able to see any of your posts, comments, or likes. They cant create new posts on your timeline, leave comments, or like anything you post. You cant do that for their account either. They wont be able to message or call you, and you wont appear in their Facebook searches. However, old conversations will still be in your inbox, but the name of the person you blocked will not be clickable. Its important to note that blocking someone on Facebook is reciprocal, so you also wont be able to do things like start a conversation with them or add them as a friend.
