If you feel bad about ignoring someone’s messages on Facebook, you should know that you’re probably ignoring a lot more messages. Only a few people know that Facebook users don’t receive every message sent to them.
To find these messages, follow the steps.
Open the Messenger app and go to Settings.
The social network makes a selection of messages sent by people who are not in your list of friends. Facebook message requests that might be considered questionable are put here similarly as questionable mail is put in Spam.
