The server turned away our test request identifying as GPTBot and ClaudeBot. Our test came from Cloudflare's network, not from the AI company, so the real crawler may be treated differently.
From robots.txt rules for the homepage (RFC 9309). robots.txt is a request; this does not show what any AI company does. Part of Kavel's AI crawler study, built with AI.
