The purpose of the broad list is removing AI-generated content from search results, so that the user doesn't have to wade through (as much) slop to find the human-created content they're looking for.

While I applaud the honesty of sites that are open about their content being AI generated, that type of content is never what I'm looking for when I search, so if they're in my search results it's just more distraction/clutter drowning out whatever I'm actually looking for. Blocking them improves my search experience slightly, even though there is of course still lots of other unwanted results remaining.

Granted, I definitely count as an AI hater (speaking of LLM's specifically). But even if I weren't, I don't think I'd be seeking it out specifically using a search engine; why would I do that when I could just go straight to chatgpt or whatever myself? Search is usually where people go to find real human answers (which is why appending "reddit" to one's searches became so common). So I see this as a utility thing, more than a "I am blocking all this just because I hate it" thing. Although it can be both, certainly.
