215,000 Fake AI Buying Guides Are Poisoning RAG Procurement Pipelines

Trellner Research found that three coordinated websites published over 215,000 machine-generated software recommendation pages designed to be retrieved by AI systems rather than read by humans. Testing across 380 software categories showed that 59.8% of citations returned by Perplexity pointed to domains outside the top 100,000 most-visited websites. The findings expose a direct integrity risk in any enterprise workflow that uses AI-grounded search to inform vendor selection or procurement research.
