Most Facebook users still in the dark about its creepy ad practices, Pew finds

A study by the Pew Research Center suggests most Facebook users are still in the dark about how the company tracks and profiles them for ad-targeting purposes. Pew found three-quarters (74%) of Facebook users did not know the social networking behemoth maintains a list of their interests and traits to target them with ads, only discovering this when researchers directed them to view their Facebook ad preferences page. A majority (51%) of Facebook users also told Pew they were uncomfortable with Facebook compiling the information. While more than a quarter (27%) said the ad preference listing Facebook had generated did not very or at all accurately represent them.
