Spawning AI offers Kudurru, a network-based tool that detects web scrapers collecting images for AI training and allows website owners to block them or send back substitute images.
Details
Kudurru works by having member websites analyze incoming web traffic to identify and blacklist IP addresses associated with AI data scrapers. Website owners can choose to block detected scrapers outright or optionally serve them alternate images (a technique sometimes called 'data poisoning'), which can corrupt the data a scraper collects. Sites enrolled in Kudurru are also automatically added to Spawning's Do Not Train Registry. As of November 2023, Kudurru was in beta and available as a WordPress plugin blocking over 400 identified scraper bots.
