As with all power laws, my guess is that this kind of incredibly low quality robocalling is being done on a MASSIVE scale by a single digit number of orgs globally - someone somewhere has figured out an essentially bulletproof way to do scam robocalling, number validation and so on on a gigantic scale, such that the quality matters less. I wonder how much global productivity in terms of time spent paying attention to incoming calls or texts would increase if you bonked whoever is orchestrating such a scheme.
