Unless, that is, they were from CEO Mark Zuckerberg.
Facebook deleted messages Zuckerberg sent on the platform from the inboxes of people who received them, according to TechCrunch. The news site said it has seen the receipts in the form of one-sided dregs of conversations and email notifications alerting some users that the Facebook CEO had been in touch.

Facebook admitted retracting its CEO's messages for security reasons. It deployed a Snapchat-esque effect, by which messages self-combusted after a certain length of time.
"After Sony Pictures' emails were hacked in 2014 we made a number of changes to protect our executives' communications," a Facebook spokesman said over email. "These included limiting the retention period for Mark's messages in Messenger. We did so in full compliance with our legal obligations to preserve messages."
Facebook might have technically been playing by the rules, but not informing users that Zuckerberg's messages were being deleted from the inboxes could be seen as playing fast and loose with their trust. It's, given that it's currently pursuing a significant trust-rebuilding mission.
Just this week Facebook announced a, following revelations that user data in the past.
Zuckerberg has been stung before when his private messages from 2004 were leaked in 2010. It was an embarrassing incident for the CEO, who had to apologize for calling his fellow Harvard students "dumb fucks" for trusting him with their data. It wouldn't be surprising if measures were put in place to prevent similar incidents happening again.
