【Watch Playboy Playmates Unwrapped (2001)】

A disturbing advertisement slipped through the Snapchat review process,Watch Playboy Playmates Unwrapped (2001) despite the ad's flippant reference to violence against women, and to Chris Brown's infamous domestic assault against his then-girlfriend Rihanna.

Screenshots of the advertisement for a "Would You Rather!" game appeared on Twitter over the weekend and into Monday. The image asks users whether they'd "Slap Rihanna" or "Punch Chris Brown," an obvious reference to the 2009 assault.

The ad caught the eye of activist Brittany Packnett and, through her, former first daughter Chelsea Clinton. She called the ad, "just awful."
