AirTag traces 1,000-book mystery order to Amazon's AI scanning hub
404 Media hid an AirTag inside an order of roughly 1,000 books bought anonymously via Biblio, then tracked it to Amazon's VGT3 facility in Las Vegas. Worker threads there confirm the site destructively scans large volumes of books. It is the strongest proof yet that price-insensitive bulk book orders, long suspected in the trade, quietly feed AI training pipelines. Sellers now have a concrete signal for spotting anonymous AI-data buyers.
