Reporting domain name registrars for abuse inaction?

Namecheap.com has become the domain registrar of choice for SMS scams in Australia. This includes everything from fake news sites encouraging people to download malware to phishing scams.

I’ve reported multiple domains to Namecheap and the “legal” team cares as much as telling me to go bother someone else about it even though it’s in violation of their TOS. Namecheap of course also hides the WHOIS information so it more or less stops any action from being taken.

I’d like to think ICANN requires registrars to be a bit more proactive about abusive domains, so the inaction is fairly confusing.

Is there any way to try to have Namecheap enforce their abuse TOS? As it stands it appears to exist only for show.
