It is probably obvious to most people that certain personal information should be tightly protected — especially bank details, health records, and passwords. The motivation might be to protect us from criminal activity, embarrassment, or just because it is not anyone else’s business.

And that means that there is an entire industry worth billions of dollars devoted to finding everything out about YOU. Your friends. Your shopping habits. Where you live and who you live with. Everything is up for grabs and harnessed for one simple reason. To make it easier to target you with adverts persuading you to buy things you might not purchase otherwise.
