Claims a practical 100% detector for images from ThisPersonDoesNotExist by exploiting the site’s global cache and indexing every served face. Uses a $100 Jetson Nano to download ~72k images/day, stores FaceNet vectors in Elasticsearch kNN, and matches suspicious profile pictures to a 15–16 million image corpus to return a visual match and an exact timestamp of generation. Works in real runs but only for images generated while the downloader is active.
