For the chumps who have given in to being on Facebook-
If you go to https://www.facebook.com/ads/preferences it gives you all the things Facebook thinks you like and uses to choose adverts. Most of them are really weird.
It thinks I like exorcism, rituals, miracles, lasers, perfection, ruins and “cosmopolitan distribution”. For food I only like water and grapes. Therefore Facebook thinks I have mystical powers. My friend found he just had the word mammal and some animals like bats and chickens.
