How can you stop someone from contacting you?

If someone’s bothering you on Facebook, the best way to stop them is to block them. Learn more about blocking. Other ways to limit someone's ability to contact you include:

●        Unfriending them: Only your friends can post on your timeline. You can also change your settings to prevent anyone from posting on your timeline.

●        Blocking their messages: When you block messages from someone, they'll no longer be able to contact you (ex: send you messages, call you) in Messenger or in Facebook chat.
