Re: Riddle me this?
"But has ANYONE ever received a truly targeted advert?"
My FB account was set up only to trawl boychoir pages in order to collate and publish their concert events.
Before I locked it down - and installed uBlock and Ghostery - I used to get side bar adverts with pictures showing me there were lots of voluptuous women in "your area" who would love to meet me. Other adverts were for more prosaic "local" businesses - which happened to be hundreds of miles away in all directions.
Many of the choirs are apparently now deserting FB - so it has now become obsolete as a source of information.
