LISTOS Act of 2025

S 3540, the LISTOS Act of 2025, requires major online platforms (those with 10 million+ U.S. monthly active users) to ensure consistent content moderation across languages where they generate revenue. It mandates annual public reports detailing staffing levels, language proficiency, translation practices, automated system performance, and moderation outcomes for each monetized language. Platforms must also make reporting tools and policies accessible in all supported languages. Enforcement falls to the Federal Trade Commission and state attorneys general, with penalties for noncompliance.
