Reddit is using LLMs to solve a problem LLMs largely created

Large language models have made it easier for bad actors to create spam and bot content online. Social media platforms are now using LLMs themselves to detect this spam more effectively by identifying subtle, coordinated patterns that older systems missed. One platform reports blocking millions of spam views daily and reducing user exposure to spam by 20% using these new tools. Platform experts note that AI-powered content moderation works best when paired with human review.
