Single crafted blog post poisons Google/Gemini/ChatGPT outputs (e.g., turning you into a "world-champion hot-dog eater" or biasing health/finance advice); Google updates spam policies to fight back.

Why It Matters
Weird real-world behavior artifact (one blog post hacks truth at scale) at intersection of internet culture, media institutions, and AI trustworthiness; changes how information/identity/reality propagate. Mischievous cat-and-mouse with serious implications for law/media. Builder utility in understanding poisoning vectors.

BBC Future investigation (May 19 coverage), HN signal, explicit demonstration of one-post manipulation scaling to AI Overviews.
