In a proposed class action lawsuit, a Californian citizen charged Fliff with operating an unlawful sportsbook in the state. According to the complaint, using the app cost him more than $7,000. He is requesting more than $5 million in damages for both himself and any other impacted parties. Additionally, an injunction is requested to prevent Fliff from conducting its contests across state boundaries, which is said to be a breach of a federal directive.
