The Ninth Circuit has held that Twitter is not liable for the acts of Twitter. The plaintiffs in Fields v. Twitter, No. 16-17165 (9th Cir. Jan. 31, 2018) had alleged that Twitter was liable under the Anti-Terrorism Act by providing material support to ISIS. The alleged support provided by ISIS was the provision of Twitter accounts and direct-messaging services. The district court dismissed the action and the Ninth Circuit affirmed, finding that the plaintiffs had not made an adequate showing of proximate cause.
