Is phone number enumeration now considered a vulnerability? Really?

I know, remember when the telco's just published those in books every year?

But you had the option of having an unlisted or unpublished phone number. To give one datapoint, in Los Angeles in the 1980s about half of all numbers were unlisted. I would expect that the unlisted rate was much higher in big cities like L.A. compared to the rest of the country.

What I find fascinating is that people paid for privacy. Yes, indeed, people paid several dollars extra per month to maintain an unlisted/unpublished phone number. Today very few people are willing to pay actual money for privacy.

funny thing is, there's probably a decent percentage of people here that don't remember this
