This guide walks the taxonomy: headless browsers, residential proxy fraud, click farms, LLM-driven web agents, incentivized traffic, and the growing category of AI-generated engagement optimized specifically to pass platform quality filters. Each type is described by signature, cost profile, and the reporting field it inflates.
