The purpose of DNS is to spread scams

It seems way more plausible to do detection and blocking separately from registration. Domain registration is when you have the least information about intent; the author acknowledges this in their example of hiding malicious content in a subdomain.

There are DNS providers whose resolvers will block newly registered domains or domains whose content has been identified as fishy (or whose content hasn’t yet been assessed).

I’d like a world where scammers are stopped after they lock in a visible name and spend money.
