Kim Kardashian has a long history of social media notoriety. But her most serious transgression yet didn’t violate Instagram’s terms of service—it violated federal law. After Kardashian promoted prescription morning sickness pills on her Instagram account, the Food and Drug Administration sent her a stern warning demanding she take the post down immediately. Kardashian is paid by Duchesnay USA to promote the drug, called Diclegis—but her Instagram post touted its benefits without mentioning its associated risks. As it turns out, advertising prescription drugs without noting their side effects is against the law, even when a reality star does it. Kardashian promptly removed the offending post.
