KIDS Act Imposes Negligence Standard on Age Knowledge Across KOSA, SAFE BOTS, and SCREEN Provisions

Congress bundles KOSA revisions with SAFE BOTS and SCREEN Act sections that trigger obligations once a platform reaches constructive knowledge of minor users. The bill text defines children as under 13 and teens as 13-16, requiring specialized controls, moderation, and chatbot restrictions whenever the negligence standard is met. Smaller operators lack resources to litigate after-the-fact determinations by courts or the FTC.

Age-estimation deployments exhibit documented error rates above 15 percent for users under 18, with elevated failure rates for darker skin tones, disabilities, and gender-nonconforming individuals per NIST biometric studies from 2023-2025. Platforms respond by shifting to ID uploads or facial scans to reduce liability exposure. This pattern replicates prior state laws in Utah and Arkansas where services defaulted to universal verification.

Encrypted messaging services face parallel pressure under the bill's reporting and moderation clauses, creating conflicts with end-to-end encryption architectures. Startups and open protocols absorb disproportionate compliance costs compared to incumbents that already hold user data. Operational outcome is centralized identity infrastructure rather than granular, service-specific tools.

Implementation begins 180 days after enactment, with first FTC rulemaking notices expected within nine months and initial enforcement actions targeting non-compliant platforms by Q3 2027.
