Facebook Thinks You’re Gay Or A Drug User Based On Three ‘Likes,’ Study Says Facebook advertisements take one swift look at a few of your “likes,” and make a decision about your sexual orientation, drug use history and more - whether you purposefully post it on your profile or not, according to a new study out of Big Data. This is a really bad way to tell if someone is queer. For instance, if a person on Facebook “likes” Lady Gaga, Glee and the Human Rights Campaign, Facebook is likely to assume that person’s sexuality is gay. They make these assumptions to exploit information about someone’s personal characteristics that they haven’t made public on the internet - such as being gullible, introverted, female, a drug user, or gay... I don't like any of those 3 things.
