Reddit's AI Tools Block 23 Million Spam Views Daily While Bias Concerns Mount

Reddit's AI tools are now blocking 23 million spam views daily, cutting user exposure by 20%, while new research from Oxford and the University of Potsdam warns that the same large language models powering these defenses may be introducing subtle bias into social media content.

• Reddit is now blocking 23 million spam views per day using AI-powered detection tools, reducing users' exposure to spam by 20% between January and March.
• Large language models are being deployed to identify coordinated spam patterns and detect hate and violent content in under five seconds, with greater accuracy than older systems.
• New research from Oxford and the University of Potsdam warns that LLMs introduce subtle bias into social media content, raising concerns about Reddit's dual role as both an AI spam fighter and a platform that licenses its content to AI companies for model training.
