Snapchat is in hot water after hosting an add making a game of domestic violence that featured photographs of Rihanna and Chris Brown.

The ad was for the mobile game “Would You Rather,” which asks users a series of questions, sometimes offensive. The ad said, “Would you rather slap Rihanna” or “punch Chris Brown.” While this question doesn’t run astray of what many popular Instagram meme pages ask, Rihanna took particular offense to this content.

“This advertisement is disgusting and never should have appeared on our service,” a Snapchat spokesperson said in a statement. “We are so sorry we made the terrible mistake of allowing it through our review process. We are investigating how that happened so that we can make sure it never happens again.”

Snapchat has an automated ad-buying platform. But company policy states, “All ads are subject to our review and approval.” It also says it prohibits “Shocking, sensational, or disrespectful content.”

Investors apparently heeded the call from Rihanna to toss the app and threw away some stock. Snap Inc’s stock prices fell around 4 percent on Thursday, wiping out nearly $800 million from its market value, reports CNN. By Friday, it had rebounded some, but closed the week with a 1 percent loss.
