I have considered making a website that specifically enforces the use of a hardware passkey such as a yubikey since you can verify that it it is a real device signed by yubico meaning that if you want a bunch of users to come discuss a subject they are verified by means of having to purchase a physical key. Obviously, there is nothing stopping someone from buying a bunch of yubikeys but you can then ban said users with those yubikeys
