I think there is less intelligence in the system than that. I get a lot of robocalls in Spanish, a language I do not know. (and other than living in California, there's not a lot about me that would suggest I know Spanish?) I mean, it is a small portion of my robocalls, but it's still several a week, when I answer unknown numbers.
But, I get a lot of robocalls; 3 calls a day is light. So clearly, some people get more calls than others, I'm just saying, I don't think the filtering criteria is particularly smart.
that's sort of what I was getting at? I mean, I think that we have the same problem we have with spam; it's so cheap to send it that it doesn't really matter that only a tiny fraction of those who receive the spam might actually be credible targets; but it's so cheap that it doesn't really matter.
