I live in the US and we’ve got elections coming up. Every day for the past several months, I get 3-8 text messages from political campaigns per day. I block them every time, yet they keep coming in.

My question is NOT how to stop them, but what happens to those numbers that I, and surely hundreds and maybe thousands of other people have blocked? What if an actual person gets that phone number and needs to call people? What happens then?

Because on a long enough time line, all numbers will have been used for spam.
