Probably ignoring things like robots.txt, I'm guessing? But I'd be curious what exactly the list of things is, and if it's growing. Would it go as far as ChatGPT filling in CAPTCHAs?

autocomplete="off" is an instance of something that user agents willfully ignore based on their own heuristics, and I'm assuming accessibility tools have always ignored a lot of similar things.

A lot of publishers do not care about blind people, and would prefer that they be unable to use AI to read.
