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.
He dumped his entire blocklist, which must include a bunch of sites that he finds personally annoying.
Here is the list of domains owned by the 16 companies discussed in the post that he linked to: https://codeberg.org/bbbhltz/16CompaniesFilters/src/branch/m...
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.
Sound good?
