I took a look at the linked block list[0]. There's a lot of junk in it, but I'm also seeing a lot of sites that have, in my opinion, pretty decent content.
My approach with Kagi is just to block SEO spam when it shows up in my results, but I don't think good SEO means it's a bad site with no useful results.
Yo, I'll spend a bit of time splitting the lists up.
Obviously, there are a number of websites in there outside the 16 Companies from the linked article in my post, and the Kagi top blocked domains that I've added myself as I scroll through search results.
I understand that my taste may not be for everybody so will make it clearer in the post and give a bit more options.
Indeed, I despise SEO spammy sites and block them aggressively in Kagi, but I see many sites on there that do have good content, often paired with good SEO and lots of ads. I have blocked sites that have good content due to invasive ads before so I'm not one to cast stones, but I wouldn't blindly use this list as you're likely going to be cutting out some potentially good sources.
