5% of 30,177 measured domains disallow amazonbot in robots.txt at the site root. Separately, and independently of robots.txt, 17.4% of 30,185 reachable domains refuse an AI crawler user agent at the network edge on two consecutive probes from different locations - a refusal the site's own robots.txt does not declare and its owner often has not chosen.

What it is definition
Crawls for Amazon product and Alexa answers and may use the content to train Amazon AI models.
Amazonbot is operated by Amazon and classified here as model training. These agents collect text and images that may end up in a training corpus. Disallowing one withholds new content from the next model. It does not withdraw anything collected before the disallow, and it does not remove the site from any answer engine.
Disallowing amazonbot withholds content crawled from that point on from Amazon's training data. It does not withdraw pages collected in earlier crawls, it does not reach copies already sitting in third-party datasets, and it does not remove the site from any answer surface.

This list is served from a cache rebuilt just now. It is discarded the moment a rescan records a policy change for this agent, so a site that has just changed its robots.txt will drop off it within one scan rather than waiting for the cache to expire.

Amazon runs 3 agents in this registry, and they do different jobs. Blocking one says nothing about the others.
Common questions answered
Does blocking Amazonbot remove me from Alexa and Amazon search?
No, not by itself. Amazonbot collects content for training, not for the index that answers questions. Amazon's answer surfaces are governed separately by amzn-searchbot and amzn-user, which stay allowed unless you disallow them too. Content collected before the disallow is not withdrawn.
How do I verify Amazonbot requests are genuine?
Amazon documents reverse DNS verification. The source address must resolve to a host under amazonbot.amazon, and a forward lookup of that host must return the same address.
