Rihanna has accused Snapchat of “intentionally” shaming victims of domestic abuse.
The singer was the subject of an advert on the platform which asked users if they would “rather slap Rihanna or punch Chris Brown”.
The ad, which was for a game, appeared to reference Chris Brown’s conviction for assaulting Rihanna in 2009 while they were dating.
Newsbeat has contacted the owner of Snapchat – Snap Inc. – for comment.
Rihanna posted a lengthy comment on an Instagram Story saying she was “trying to figure out what the point was with this mess”.
“I’d love to call it ignorance, but I know you ain’t that dumb,” she wrote.
The company’s share price has fallen by more than 4% since Rihanna’s statement.
Snap previously apologised, telling Newsbeat the advert was published “in error” and had been removed immediately.
“The advert was reviewed and approved in error, as it violates our advertising guidelines. We immediately removed the ad last weekend, once we became aware,” the company said.
Rihanna accused Snapchat of “intentionally” shaming domestic violence victims.
“This isn’t about my personal feelings, cause I don’t have much of them… but all the women, children and men that have been victims of DV in the past and especially the ones who haven’t made it out yet.
“You let us down! Shame on you. Throw the whole app-ology away.”
The advert was widely criticised online on Monday.
Twitter users described it as “disgusting”, while the daughter of former presidential candidate Hillary Clinton said it being approved was “awful”.
Snap’s advertising policy is outlined on its website and includes information on its review procedure.
“All ads are subject to our review and approval. We reserve the right to reject or remove any ad in our sole discretion for any reason.
“We also reserve the right to request modifications to any ad, and to require factual substantiation for any claim made in an ad,” it says.
There is also a list of banned content, including “shocking, sensational, or disrespectful content”.
Snap Inc’s shares fell by almost 8% – wiping £1bn off its market value – when Kylie Jenner tweeted that she was “sooo over” the social media platform in February.
