I had the same feeling. It seems the two things here in question is my phone number (which luckily I never gave fb), and my email which it seems every spammer in the world already seems to have? I noticed this even back when phonebooks were a thing that a 'private' number was not something random people should call. Yet the reality is that number is kind of public but not. If you did accidently call one you would get 'how did you get this number' from the person you called. Judging by the amount of phone calls I get these days. They have also already correlated a huge number of these. Short of me changing my number every few years there is not much I can do. I am getting cold calls on property I bought 20+ years ago and them asking if I want to sell. At the bottom of this though is the 'data' these companies are scouring on us. Then cross correlating it. I have for the past few years come to the conclusion data is harmful to keep for both the end users and the companies that do it. Companies like google and fb seem to be of a very different opinion. Companies should be going into collecting data with 'how do we get rid of it after some period of time', not lets buy more HD to keep it on.
