AdsBot-Google
AdsBot-Google is the tool or developer fetch run by Google: Google Ads quality. Its operator documents how to verify it: Google special-crawler ranges (shared feed) + reverse DNS to google.com. A reverse DNS lookup on the source address must return the operator's domain, and a forward lookup on that name must return the same address.

Allow or block it in robots.txt
User-agent: AdsBot-Google Disallow: /
User-agent: AdsBot-Google Allow: /
Add a group that names it: "User-agent: AdsBot-Google" followed by "Disallow: /". A crawler follows only the most specific group that names it, so once a group names AdsBot-Google, rules under "User-agent: *" no longer apply to it; repeat in that group any Disallow lines you still want.
What blocking it changes
No. It is a third-party tool's crawler. Blocking it changes what that tool knows about your site, not anyone's AI answers.
