Reddit is employing its own AI tools, specifically large language models (LLMs), to detect and combat AI-generated content and spam on its platform. These systems have been effective in blocking millions of spam views, posts, and inauthentic votes daily, leading to a significant reduction in user exposure to spam. The AI also identifies suspicious account activity and coordinated fake behavior, with enforcement actions now taking less than five seconds, thereby reducing harmful content exposure by over 40%. This initiative follows Reddit's previous efforts to address AI scraping and experimental use of AI on its site. AI
