It looks like Facebook's ever-changing privacy functions aren't just frustrating for you and me—even Mark Zuckerberg's sister (a former Facebook official herself) can screw up. A family photo Randi Zuckerberg posted on her Facebook page was tweeted by a friend of a family member, upsetting Zuckerberg, reports Buzzfeed. "I posted it to friends only on FB. You reposting it to Twitter is way uncool," wrote Zuckerberg on Twitter (now deleted).
The original poster deleted the pic (too late, of course ... this is the Internet) and said she did not realize Zuckerberg considered it private since it was posted where she could see it. Despite the confusion, Zuckerberg refused to call the mini-drama a Facebook settings issue. "Digital etiquette: always ask permission before posting a friend's photo publicly. It's not about privacy settings, it's about human decency," she tweeted.
