A good chunk of Facebook's history is simply gone—at least from anywhere you'd expect to find it. That's because many of CEO Mark Zuckerberg's posts have vanished from the site, including vital ones reported by the media and everything from 2007-2008, Business Insider reports. Among the missing are Zuckerberg's promise to let Instagram grow "independently" after Facebook acquired it in 2012 (a commitment that didn't last) and his famous reaction to backlash over the 2006 launch of News Feed, which has since made billions of dollars in advertising: "Calm down. Breathe. We hear you," he wrote at the time. Asked about the erasures, Facebook blamed bad tech.
"A few years ago some of Mark's posts were mistakenly deleted due to technical errors," says a company rep. "The work required to restore them would have been extensive and not guaranteed to be successful so we didn't do it." The rep adds that "for years" Facebook has archived the posts "on our blog and in recent years on our Newsroom." Indeed, there was such a blog (an example is archived here) and now the Newsroom, but many posts remain missing, and using the "note" feature to find them can be a long slog. The posts turned up missing at a time when Facebook is embroiled in scandals over security and privacy, notes CNET. (Read more Facebook stories.)
