Relying on Google for this is actually not beneficial, as discussed here many times: https://hn.algolia.com/?q=Google+safe+browsing

If the registrar tracks this information, a possibly helpful course of action would be to notify or warn the domain owner that they are on the list.

In the modern adversarial web, I do not want a registrar that proactively disables my domain because of some third party report.
