Brands and spammers are increasingly leveraging AI to manipulate Reddit by flooding subreddits with promotional content, a practice known as Generative Engine Optimization (GEO) or AI-engine optimization (AEO). This strategy aims to influence AI chatbots, such as ChatGPT and Google's AI search tools, which frequently draw on Reddit data for responses. Moderators of the r/biohackers subreddit, for instance, recently restricted posts about certain supplements after discovering companies seeding the community with content designed for AI scraping. Companies like RedRover openly advertise using AI agents to mass-publish content on Reddit and blogs to boost search rankings. The accounts used in these campaigns are sophisticated, designed to appear human with posting histories and organic engagement. While Reddit's safety teams employ automated tools to detect and remove spam, moderators report that the tactics have become so advanced that manual pattern recognition is often required. Reddit has also updated its robots.txt file to block unauthorized AI scrapers, though this is not legally enforceable. Ironically, Reddit has simultaneously entered into licensing agreements with AI companies, including OpenAI, to allow their models to train on Reddit's content for commercial purposes, creating a dual approach to AI data utilization.
