(NEW YORK) -- Randi Zuckerberg, the former marketing director of Facebook and sister of the company's CEO, Mark Zuckerberg, was not happy at the end of her Christmas Day.
A photo she posted to her Facebook account of her family -- including Mark -- playing around with Facebook’s new Poke app, ended up on Twitter.
The photo was tweeted by Callie Schweitzer, a marketing executive at Vox Media, who thought it was a public photo on Facebook. Schweitzer followed or subscribed to Randi's public Facebook feed and thought the update was public.
But it wasn’t. According to Buzzfeed and Randi’s tweets, Schweitzer was friends with another one of the Zuckerberg sisters and because she was tagged in the photo, Schweitzer was able to see it.
“.@randizuckerberg demonstrates her family’s response to Poke #GAH,” Schweitzer tweeted along with the photo.
It didn’t take long for Randi to respond.
“Not sure where you got this photo. I posted it to friends only on FB. You reposting it to Twitter is way uncool,” she said on Twitter.
Schweitzer clarified that she thought it was public, apologized and removed the photo promptly. But the photo wasn’t removed entirely. Many websites, including Buzzfeed, Business Insider, Mashable and Gizmodo, ran the photo. VentureBeat even said the Zuckerbergs are tripped up by Facebook’s privacy settings.
However, Randi tweeted that “it’s not about privacy settings, it’s about human decency.”
The snafu illustrates something Facebook has started highlighting in its recent privacy controls overhaul -- that your Timeline is separate than other places on Facebook and that tagged photos can still be viewed by others.
Starting last Friday, Facebook rolled out its redesigned and cleaner privacy tools. One of the additions included educational messages, which pop up when you untag a photo. The message tells users that the photo still might be visible by others.
