robots.txt is a request, not a lock: well-behaved crawlers read it, anything malicious ignores it. Under RFC 9309 a bot reads the one group that names it and falls back to the star group only when none does, which is why every overridden bot gets its own complete group here. Googlebot ignores Crawl-delay no matter where it appears; rate limits for Google live in Search Console, not in this file. The AI crawler list covers the crawlers site owners ask about today; new ones appear often, so check the big operators' documentation when one matters to you.

Crawl policy

Default, all robots
Crawl delayA line every group carries; Googlebot ignores it entirely
Optional, absolute http(s), up to 2048 characters
