Amzn-User/0.1How to block Amzn-User in robots.txt
Add this to the robots.txt file at the root of your site:
Block Amzn-User
User-agent: Amzn-User
Disallow: /Explicitly allow Amzn-User
User-agent: Amzn-User
Allow: /What blocking changes: A robots.txt block is generally not honored for user-triggered fetches; blocking at the network/WAF level is the reliable option. Doing so stops Amazon's assistants from reading your pages on request.
