At this point I can only operate off of my memory. The Facebook ads privacy settings have changed quite a few times. For several years there was a page that, if I am remembering correctly, offered to allow you to opt-in to interest-based ads. For most of that time, at least for me, the actual "button" remained grayed-out and I received a message that said that I was unable to join the program at that time. How does one characterize this other than, "if I cannot opt in, surely my information is not being used in this way without my permission"?
