Reddit fights back against AI SEO spam invasion

Reddit is becoming ground zero for a new wave of AI-powered search spam, as brands deploy fake accounts to manipulate responses from AI tools like ChatGPT, Perplexity, and Google’s Gemini. A recent investigation by *The Verge* revealed how a user named *Primary-Taro4254*—later exposed as a likely bot—flooded skincare subreddits with unsolicited praise for Honeydew Labs’ hypochlorous acid spray. The account’s repetitive, generic endorsements across unrelated threads mirrored classic spam tactics, prompting r/SkincareAddiction moderators to ban Honeydew Labs-related posts and flag the bot for review.

This surge in AI SEO tactics isn’t isolated. Semrush data shows Reddit is the most-cited domain by major AI chatbots, surpassing even Wikipedia, as AI tools increasingly funnel users toward Reddit-style community insights. With Google’s AI Overviews now dominating commercial search queries, brands see Reddit as a prime target to game AI responses. Moderators like Maya Adivi of r/SkincareAddiction are now deploying stricter filters and AI-detection tools to curb inauthentic promotions, but the cat-and-mouse game is just beginning.
