Pretty easy to display one thing to verified browsers (just latest few user-agents from the 10ish different mainstream browsers on the 3 main OSes) and another to anything else.

Yes AI scrapers can easily spoof user-agent, but they fall out of date as the browser updates.

Bit harder to catch them in tarpits and then serve nonsense to whoever ever triggered the tarpit.

and browsers forcibly auto-update
