Major social media companies, including Facebook and Reddit, are seeking to dismiss the lawsuit that Fox 29 anchor Karen Hepp has filed, alleging the companies allowed an image of her to be used on a dating website and erectile dysfunction advertisements without her consent. The dispute raises several unsettled issues about the potential liability of online content providers.

On Monday, Facebook, Reddit and GIPHY filed briefs outlining why the case Hepp v. Facebook should be dismissed. The lawsuit is pending in the U.S. District Court for the Eastern District of Pennsylvania before Judge John M. Younge.
