It’s a good thing that they know i love chocolate chip cookies my “Friend” baked, a painting by my cousin, and Aunt FeeFee’s new haircut.
It appears you don’t understand how data mining works.
Chocolate chip cookies - Nabisco, cookie manufacturers, cooking supplies stores may be interested in you.
Paintings - art supplies, museums (yes, for fundraising), art dealers may be interested in you
Hair cuts - BoRicks, Bubbles,Vidal Sassoon, Miss Clairol may be interested in you.
Now multiply that’s by hundreds of millions of other Facebook users and. You’ve got quite a lot of valuable data that businesses can profit from.
And that’s just from 3 examples you pulled out of your a$$.
As a corporation, I request searches of users with “likes” relevant to my business and Facebook has the capacity to churn it out. All for a fee, of course.
At least the survey takers at the mall would pay you 5 buxs for you answers. You give this stuff up for free, every day.
