Correct. Google indexing your web page is rate limited for this reason, and you can even include a directive in your robots.txt to specify your own rate limit if you'd like the intervals to be longer (or shorter). The AI scrapers completely ignore your robots.txt. Except, I am certain, for abusing it as if it were a site map. Anything you list there is simply a target you've revealed to them. ("Hey, robots.txt says we shouldn't crawl /foo/bar.html. That means there's a page there! Let's hammer it with 900 page load requests per second!")
