I still remember, around a decade or two ago, going through page after page of results to look for the exact page I wanted, and somewhat often getting that result. Now, if I'm very lucky, I'll find that result; otherwise, I'll probably get a CAPTCHA-hellban instead.

It's very ironic that a search engine, which is supposed to be helpful precisely for the things that are hard to find, seems to actively sabotage your efforts at such deep searching.
