I guess this is what happens when you take shortcuts to privacy.

Randi Zuckerberg, older sibling to Facebook's head honcho and the social network's former marketing director, is the latest in an exhaustive line of users to have been burnt by Facebook's byzantine privacy settings.

A private family photo posted last night by Zuckerberg was made public by Twitter notable Callie Schweitzer, stoking Randi's ire.

"@randizuckerberg demonstrates her family's response to Poke #GAH," Schweitzer wrote.

"Not sure where you got this photo," Zuckerberg tweeted at Schweitzer. "I posted it only to friends on FB. You reposting it on Twitter is way uncool."

But Schweitzer wasn't to blame for the breach: "I'm just your subscriber and this was top of my newsfeed. Genuinely sorry but it came up in my feed and seemed public," she explained.

Zuckerberg soon put two and tagging together. "I think you saw it b/c you're friends w/my sister (tagged.)," she surmised.

Schweitzer nonetheless apologized for making the private moment public, noting that she would "hate" for the same to happen to her.

Zuckerberg accepted Schweitzer's apology, and, after a quick consultation with her younger brother, announced a sweeping overhaul to Facebook's obviously broken privacy settings.

Just kidding, she deleted the entire exchange and wrote this:

Digital etiquette: always ask permission before posting a friend's photo publicly. It's not about privacy settings, it's about human decency.
