I read the page you linked, I see nothing that says they allow registration of domains or won't remove a domain they kicked off their other services.
The page does highlight abuse reporting - from there is a link to a page with a neat graphic that shows some of their services they feel are in a grey area of responsibility (https://www.cloudflare.com/trust-hub/abuse-approach/ ) and hand wavy infrastructure is important blah blah..
but then you get to the next section and it lists a to of stuff they block without a court order (and a couple they block with) -
Now does that page relate to the other services and not their domain registration is that what you are implying?
