A new more grounded list focused on specifically blocking content farms and similar low quality sites.
A nice alternative to this very broad anti ai list: https://github.com/laylavish/uBlockOrigin-HUGE-AI-Blocklist
Edit: Oh I should mention I found it through reddit and there is some good discussion there where they describe how they find stuff etc: https://www.reddit.com/r/uBlockOrigin/comments/1r9uo3j/autom...
So there is a spreadsheet of websites. That is very interesting. There was an article here sometime ago about a media group who have so many super SEOd websites. They all have common footer text. I searched and added as many as I could find in uBlacklist. I have a gist listing them and how I searched for them. You might find that useful.

The broad list seems to just be a hater list. It's not trying to cover cases of deception (passing off AI material as if it's something else), as it includes sites which are very open about what kind of content is on there.
