Does this actually do anything? A computer that can dial all phone numbers in the US is not hard anymore. (the computer will probably get all numbers in North America, but what do scammers care?)
In the last year I've only gotten 2 spam phone calls. So either Google Fi is doing a better job at blocking them than Verizon was, or the scammers that targeted me stick to known numbers. Either way I'm not taking my chances. It was seriously frustrating being on their victim list.
