Using a host IP / A record may give you different results. Not all ADC-linked domain names will have proper DNS record setup, and many are in a whack-a-mole situation. A lot of time the registrar knows what the OSINT community doesn't know simply by checking the internal data which is only available to specific registrar. 

Let's focus on the registrar account / registrant level solution. Thanks!

To me, all checks qualify as associated domain checks. The only difference is that some of them pivot on open source publicly accessible data (like NS or MX records or public abuse reports) and others pivot on personal data, like the registrant name or email address.

As I understand, Farzy has a problem not with the associated domains check itself, but with the datapoints that are used as pivot points. If you pivot on host IP for example, it's ok. If you pivot on registrant email then it is considered more intrusive.

Maybe we can explore this specific issue further.

Is Signal Checking not already ADC?

Hi Nick, just to be clear we are not saying don’t start any kind of investigation. We are saying before you go to ADC check based on one abuse report, check these other signals. In order to do ADC you need to have access to registrar backend or database. 
These other signals I mentioned don't need access to backend it's public information. are not (I managed to gather the signals without being a registrar, I am only a detective

So in effect, to find out about those signals you don’t have to do ADC as your first action as I demonstrated. Those signals along with abusive domain could establish the trigger for ADC.
