None of the instances listed have anything like that going on. I believe that all listed instances use either https://www.cloudflare.com/products/turnstile/, https://anubis.techaro.lol/, https://git.miningtcup.me/MiningTcup/dogwaf (made by me), or nothing at all. I recommend against using instances not listed unless you know the host because there are reasons for them to not be listed. I won't elaborate on the reasons for some major instances not being on the list as I want to keep my HN account.
