It is an increasing problem. I've defaulted to never answering numbers I don't have saved unless I expect a call. If it's important they should leave a voicemail. I wanna say a few years ago it wasn't this bad, then I realized I had missed a lot of spam calls cause I had my number behind Google Voice (free with Sprint) and now it is just ridiculous.

Also idk about other states, but in FL everything is public record, so after I bought my house I've gotten spam letters and calls like crazy.
