Reddit is taking steps to address a growing form of spam tied to artificial intelligence tools that generate answers for users. Bloomberg reports that brands increasingly use “stealth marketing” by creating posts and comments designed to be noticed on Reddit and then repeated by popular AI chatbots such as ChatGPT and Gemini. The approach involves planting content that can be surfaced by AI systems when users ask questions, effectively turning Reddit into a source for marketing language without an explicit promotional tone.
Multiple outlets describe Reddit as a widely trusted platform that is frequently cited by third-party studies and by company executives when AI chatbots pull information for responses. As reliance on chatbot answers grows, the marketing strategy shifts from traditional search optimization toward content placement intended to influence how AI summarizes or quotes sources. In response, Reddit is deploying its own AI to identify and limit this type of “AI marketing slop.”
The reporting is consistent that the targeted behavior is covert brand seeding of discussions, and that Reddit is using AI-driven measures to reduce its visibility and impact on the platform and on content that may be reused by chatbots.
