Reddit is using LLMs to solve a problem LLMs largely created

Reddit has deployed LLM-based tools to combat spam, much of which is itself generated by LLMs. The platform reports blocking 23 million spam views per day and catching around 25,000 new spam posts and comments daily, with a claimed 20% reduction in user exposure to spam between January and March compared to the prior quarter. Experts note that AI-driven content moderation still needs to be paired with human review for best results.
