Meta uses AI to automatically scan and remove content that violates its rules across Facebook, Instagram, WhatsApp, and Threads — handling billions of posts per day before human reviewers ever see them.

AI now handles the vast majority of enforcement actions proactively. In January 2025, Meta reduced AI enforcement to only illegal/high-severity violations and switched to Community Notes (user-based fact-checking) for lower-severity content, reducing false positives by 75%+. LLMs now trained directly on Community Standards for select policy areas, outperforming human accuracy in tests. Q1 2025: 24.5M CSAM-related pieces removed (99.8% proactively detected). Whistleblower Frances Haugen (2021) testified that engagement-optimizing algorithms amplified harmful content. Amnesty International SEC complaint (2025) alleges Meta's systems contributed to Rohingya genocide in Myanmar.
