Are you only crawling or also scraping the website? If the sites in question only add an exception for googlebot and not other crawlers (e.g. Yahoo, bing, etc.) I would say that it is against the site owner's consent. However if the site owner adds this exception also for other crawlers, you could argue that the site owner's intent of only allowing certain crawlers has not been made explicit. In that case you'd have…

Genuinely curious: on what basis? Can you trademark (or similar) a user-agent?

If you crawl a site, index it, and then use that for commercial purposes -- all while using Google's trademark to crawl -- yes, you'll probably get a letter from Google. As for the site owner, it's on them to decide what to do with your traffic. HTTP is an open protocol and extensible. You could send almost anything in your request, as allowed by the protocol. The site owner has opened their service to the HTTP proto…

How would you get a letter from Google if you are never scraping google's sites? They would never know?

I'm not a lawyer and this isn't legal advice; but my instinct is you won't get in trouble.

Most important argument: the chrome user-agent contains the word 'mozilla'. Obviously (we argue) google isn't intending these to be accurate and instead are some kind of compatibility mark.

Are you committing trademark violation? Given the nature of trademarks, it's not clear that you are.

Are you misrepresenting yourself to the site in a way that violates the CFAA? This is probably your biggest area of risk. But you can argue the site is giving away information to google, a company whose slogan until recently was 'free the world's information'. Therefore they weren't taking plausible steps to secure the information you've scraped.

Sure, go join the realms of shady SEOs and malware, if I want to really stop you I'll know you're not coming from a Google IP range. https://www.incapsula.com/blog/was-that-really-a-google-bot-... However, consider what your ultimate end game is, if it's a website you expect visitors to find through Google or the Play store, good luck once web masters start reporting your misbehaving "Googlebot" crawler.

Unless you do it from a Google Cloud instance, that is.

What's the reverse DNS for Google Cloud IPs? Google says to check that Googlebot's IP resolves to either a .google.com or .googlebot.com domain.

It depends on what and how you're trying to crawl, it's trivial to verify a "true" Googlebot using reverse DNS:

I know of a few sites that use this as the first step (of many!) to add bots to their "naughty" list.

I handle a number of sites that require a login but need Google to index their content. I verify that Googlebot requests are actually coming from a domain owned by Google. I can't imagine that I'm the only one doing that.

It's Google's preferred way: https://support.google.com/webmasters/answer/80553?hl=en of verification it seems.
