US Congress Passes AI Deepfake Pornography Regulation Law Take It Down Act -- Obligating Platforms to Delete Within 48 Hours, First Case of Institutionalizing Corporate Social Responsibility: In the era of AI technology abuse, the US chose the clear direction of victim protection. In April 2025, the US Congress passed the deepfake pornography regulation law called the Take It Down Act. This bill introduced in January 2025 passed both chambers in late April and is awaiting presidential signature -- attracting attention as the first legislation legally imposing deletion obligations on online platforms for deepfake pornography in the US. The law covers AI or deepfake technology-synthesized pornographic images and videos using real persons faces or body parts (NCII -- Non-Consensual Intimate Images), requiring online platforms to delete such content within 48 hours of a victim request. The significance: this is the first federal US law specifically targeting AI-generated NCII; platforms must establish intake processes for deletion requests and act within 48 hours; violations carry criminal penalties; the law establishes that platforms have legal obligations regarding AI-generated harmful content not just user-generated content. The tech industry reaction: major platforms including Meta, Google, and TikTok supported the legislation after advocacy from Melania Trump and Taylor Swift victims; the 48-hour deletion requirement is operationally demanding at scale but achievable with AI detection tools; the law creates a template for state and international legislation.
