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.
