Anubis Uses Proof of Work to Block AI Crawlers

Website administrators deploy Anubis, which uses a Hashcash-like proof-of-work mechanism to make large-scale crawling by AI companies more expensive, thereby preventing servers from being overwhelmed. Anubis calls this a stopgap measure and says it will later rely on methods such as font rendering to identify headless browsers, reducing verification friction for normal users.
