The sister of Facebook founder Mark Zuckerberg is outraged over a photo leaked from her personal Facebook account.
Randi Zuckerberg posted a photo she thought was private to her own Facebook friends, but a marketing director who subscribed to Zuckerberg's updates saw the photo and posted it to Twitter. The photo showed Zuckerberg and her family reacting to the new Facebook Poke app , Mashable reported.
The marketing director has more than 40,000 followers.
Zuckerberg posted a response to the incident on her Twitter account:
"Digital etiquette: always ask permission before posting a friend's photo publicly. It's not about privacy settings, it's about human decency"
