There has likely been an evolution of war dialers. It's probably easier to blast through every possible number once a year, and sell a list of every valid number. Targeting specific area codes is probably faster and would avoid some legal problems.

    Huh. You think read receipts via RCS could make it worse? Obviously Google would probably have to make an exception to allow for this but hey "Don't Be Evil"

    I have no idea, unfortunately. Tinkering with phones and ways to exploit messaging is something I haven't done in a number of years.

    My first guess would be yes? If you ever get a blank email with only the subject line of "Hi", "Hello" or similar, it is simply a test to see if your email address is valid. It's not a stretch to assume there are also simple ways to verify valid numbers that can also recieve text messages.
