I’m not clear how owning a registrar gives them a unique view into domain registrations at other registrars. Does being a registrar come with special privileges like programmatic unmasking of “whois protection?”

They also already have a source of DNS traffic to mine for new registrations. Surely a phishing site would show up there fairly soon after registration. So does being a registrar come with more benefits than just timing?

If it does, then shouldn’t the worry be more broadly about Cloudflare potentially abusing this system to deanonymize the owner of _any_ domain, not just those they deem trademark infringing?
