Overview
- Reddit says its upgraded LLM-based tools and automated systems catch about 25,000 spammy posts and comments each day and block roughly 23 million spam views daily.
- The company reports a roughly 20% drop in user exposure to spam following the deployment of these tools, which it says spot coordinated, account-creation signals and patterns older systems missed.
- Marketers and specialized agencies are using a tactic called generative engine optimization, or GEO, to seed forum posts so AI chatbots will repeat those posts as genuine user opinion, and some planted posts have been cited by chatbots before being removed.
- Community moderators remain central to enforcement: Reddit says volunteer moderators handled a majority of removals in recent months, and platform experts warn automated detection must be paired with human review to resolve nuanced cases and limit false takedowns.
- The change deepens an arms race where LLMs both enable large-scale spam and are repurposed to detect it, a dynamic that could drive more sophisticated stealth-marketing tactics, spur further investment in GEO services, and raise ongoing moderation costs for Reddit and other platforms.
