The server's response to a request for a specific page can conflict with the directives in robots.txt. A content delivery network (CDN) or web application firewall (WAF) may return an error, rate-limit the request, or present a challenge page instead of serving the full page. These challenges can prevent GPTBot from fully accessing the site, even if the crawlers' tokens are technically allowed by robots.txt.",

I classified 4 as bot-wall responses based on their headers and body size: a challenge header on one response, bot…",
