How to Block Messages on Facebook

If you have been receiving threatening, harassing or annoying messages from a specific Facebook user, prevent that person from sending you any more messages by blocking her profile. Alternatively, if you regularly receive messages from strangers in your inbox, consider editing your Facebook message filtering settings.

Block a Profile

Blocking a profile unfriends that person and prevents her from interacting with you by sending you private messages or sharing posts on your Timeline.

Edit Your Message Filtering Settings

Much like the spam filter Web mail platforms provide to their users, Facebook comes with a message filtering feature that automatically directs potentially unwanted messages to a special folder called Other. While that feature's default setting does not filter messages from people you may know -- such as users who are friends with your friends -- the Strict Filtering setting lets you keep your inbox free from messages sent by users you did not friend.
