That works fine, until the robocallers get another batch of phone numbers to tie to their VoIP systems and the blocked ones roll back in to general use. I already get robocalls that are targeted to my own area code and region, and the same calls from multiple numbers. Cycling through those won't like add too much burden to the robot unless there's a heavy price to pay for a new batch of numbers.
