Reddit is using large language models to detect and remove spam on its platform, including material created by similar AI systems. TechCrunch reported that the company blocks 23 million spam views per day and catches about 25,000 new spam posts and comments daily. The updated tools catch spam at a higher rate than earlier automated systems, according to Reddit.
The company said it reduced users’ exposure to spam by 20 percent from January to March 2026 compared with the prior three months. “We leverage LLMs to catch the highly subtle, coordinated patterns of fake behavior and artificial hype that older systems once missed,” a Reddit blog post stated.
