The Facebook reported the disappearance of Facebook CEO and co-founder Mark Zuckerberg's old social media posts, Business Insider reported. 

"A few years ago some of Mark's posts were mistakenly deleted due to technical errors. The work required to restore them would have been extensive and not guaranteed to be successful so we didn't do it," the spokesperson said in a statement adding.

According to the statement: "We agree people should be able to find information about past announcements and major company news, which is why for years we've shared and archived this information publicly — first on our blog and in recent years on our Newsroom."
