I think it’s basically impossible to prevent AI crawlers. It is like video game cheating, at the extreme they could literally point a camera at the screen and have it do image processing, and talk to the computer through the USB port emulating, a mouse and keyboard outside the machine. They don’t do that, of course, because it is much easier to do it all in software, but that is the ultimate circumvention of any attempt to block them out that doesn’t also block out humans.

I think the business model for “content creating” is going have to change, for better or worse (a lot of YouTube stars are annoying as hell, but sure, stuff like well-written news and educational articles falls under this umbrella as well, so it is unfortunate that they will probably be impacted too).
