I use Kagi as a search engine and can just block the site from the search results.

I started using Kagi recently, and so far haven't had to block a single site. Their filters are great!

Kagi filters are great for programming, but still evolving for others. I still see a lot of pinterest results. You can block domains by adding them to Kagi blocklist through Settings -> Personalized Results -> Blocked Domains.

There's also a boost/block button right on the search results page.
