I've been consciously doing that for reference books for the past three years because Amazon is absolutely littered with AI-generated non-fiction. I have my own ideological reasons too, but the main problem is that most of that AI-generated reference stuff is just of incredibly poor quality. It's meant to saturate the platform as cheaply as possible, so no one actually does any fact-checking, editing, layout, and so on. They're not even using frontier models for that.

For example, there are multiple evidently AI-generated titles that come up on the front page if you search for "Rust programming", "cybersecurity book", etc. I guess I can't rule out that "Winston Knowles" is a real person, but I'm not gonna bet money on that: https://www.amazon.com/Cybersecurity-Career-Manual-Interview...

Oh, and here's one of the top-ranked reference books right now: https://www.amazon.com/100-000-Whys-Kids-Encyclopedia/dp/B0H... - click "read sample". Almost every illustration is wrong in some obvious way - misplaced labels, nonsensical anatomical details, etc.
