ProPublica, an independent investigative news organization, is asking users of sports betting apps to share their data in an effort to understand how these platforms encourage continued use and when they issue warnings about responsible gambling. The group is seeking at least 250 people who have used apps such as FanDuel and DraftKings to upload their transaction histories. This data will help ProPublica examine the ways in which these companies promote their services and manage user behavior. In addition to user data, ProPublica is inviting individuals with industry experience to answer questions about the business practices of sports betting companies. This includes insights into how these firms offer incentives, such as boosts or rewards, and how they handle responsible gambling notices. The goal is to uncover patterns in how these platforms operate and whether they effectively promote responsible gambling. To ensure privacy and security, ProPublica offers participants the option to communicate via Signal, a secure messaging app. This allows users to share information confidentially if they are concerned about their privacy. The project is part of ProPublica's ongoing efforts to investigate how technology and business practices impact public behavior and safety. More information about the project, including how to contribute data, is available on ProPublica's website. The initiative highlights the growing interest in understanding the influence of digital platforms on consumer behavior and the ethical responsibilities of companies that operate in this space.
