Children - As introduced, requires certain commercial online platforms, websites, and applications to maintain a content moderation system that allows users to report material harmful to minors that is not properly marked or age-restricted; makes other changes related to platform content and minors. - Amends TCA Title 39, Chapter 17, Part 9 and Title 47, Chapter 18.

SB 2398 requires large social media platforms (with 10 million+ monthly U.S. users) to implement systems allowing users to report unmarked or improperly age-restricted content harmful to minors. Platforms must acknowledge reports within 48 hours, act within seven business days (e.g., remove content or apply age restrictions), and publish semi-annual transparency reports detailing their responses. Parents or legal guardians of minors can sue platforms for failing to address repeated reports of unmarked harmful content, seeking up to $5,000 per violation, while the state attorney general may also enforce compliance through fines. The bill directly affects major online platforms and aims to improve content safety for minors through mandatory reporting systems and accountability measures.
