...Marketers spent $16 billion on location-targeted ads served to mobile devices like smartphones and tablet computers in 2017... .The data required to serve you any single ad might pass through many companies’ systems in milliseconds—from data broker to ad marketplace to an agency’s custom system... There are plenty of ways to track you without getting your permission. Some of the most intrusive are the easiest to implement... The spy in your pocket... Your telco knows where you are at all times, because it knows which cell towers your phone is near. In the U.S., how much data service providers sell is up to them.

I actually am now making notes about the advertisement I do NOT like. I am working on my own private boycott list.

My fathers family were farmers, some still are.

My dad was career Navy and was home on leave, 7 Dec 1941.
No phones in the area (SW Ohio)Put on his uniform and hitchhiked into Cincinnati for further orders.

Well into the 1960’s they still had party lines.
Don’t recall any crank phones, but many still had a HAND PUMP on the kitchen sink.
Scotsmen all, no need for some expensive plaything, the old pump worked just fine.

That initial call you get, with silence on the other end, “[is] essentially the first of the reconnaissance calls that these fraudsters do,They’re trying to see: Are they getting a human on the other end? You even cough and it knows you’re there.”
Company researchers estimate 1 in every 2,200 calls is a fraud attempt...

Every Ipad like device, every Google account has phone number attached to it. There is money to be made for people to "mine" for live numbers. I bet they have a Lobbyist that pays well too.
