Facebook messages that Mark Zuckerberg and other Facebook executives sent to other users on the social network were recently found to be deleted from those user's inboxes, according to a report in TechCrunch Friday.
Three unnamed sources speaking to TechCrunch said that messages they had previously received from Zuckerberg were no longer in their inboxes, though the messages they sent to Zuckerberg remained.
