So the easiest strategy to hamper them if you know you're serving a page to an AI bot is simply to take all the hyperlinks off the page...?

That doesn't even sound all that bad if you happen to catch a human. You could even tell them pretty explicitly with a banner that they were browsing the site in no-links mode for AI bots. Put one link to an FAQ page in the banner since that at least is easily cached

When I used to build these scrapers for people, I would usually pretend to be a browser. This normally meant changing the UA and making the headers look like a read browser. Obviously more advanced techniques of bot detection technique would fail.

Failing that I would use Chrome / Phantom JS or similar to browse the page in a real headless browser.

I guess my point is since it's a subtle interference that leaves the explicitly requested code/content fully intact you could just do it as a blanket measure for all non-authenticated users. The real benefit is that you don't need to hide that you're doing it or why...

You could add a feature kind of like "unlocked article sharing" where you can generate a token that lives in a cache so that if I'm logged in and I want to send you a link to a public page and I want the links to display for you, then I'd send you a sharing link that included a token good for, say, 50 page views with full hyperlink rendering. After that it just degrades to a page without hyperlinks again and you need someone with an account to generate you a new token (or to make an account yourself).

Surely someone would write a scraper to get around this, but it couldn't be a completely-plain https scraper, which in theory should help a lot.

I would build a little stoplight status dot into the page header. Red if you're fully untrusted. Yellow if you're semi-trusted by a token, and it shows you the status of the token, e.g. the number of requests remaining on it. Green if you're logged in or on a trusted subnet or something. The status widget would links to all the relevant docs about the trust system. No attempt would be made to hide the workings of the trust system.
