Content Moderation

Content Moderation is the hybrid system (AI/ML and human review) that monitors user-generated content (UGC), enforcing platform policies and legal compliance at massive scale.

This is a critical, hybrid process: it deploys AI/ML systems (Natural Language Processing, image recognition) to filter billions of pieces of UGC (text, video, audio) in real-time. The technology handles the volume—platforms see 500+ hours of video uploaded every minute—while human moderators manage the nuanced, contextual edge cases. The primary objective is mitigating platform risk: preventing the spread of illegal or harmful content (e.g., CSAM, hate speech, deepfakes, misinformation) to maintain user safety and brand integrity.
