Together, we analyzed his timeline. I had to see what he saw. I had to figure out why he would let this app threaten his safety. We scrolled. He follows thousands of people with posts that are about as unique as a person in skinny jeans and dark frames nowadays. Multiple selifes, party-promoter fliers, and pictures of food—disgusting food, like trays of white macaroni with eight pieces of American cheese laying across the top, impatiently waiting to be melted, with a caption that reads something like, "My grandma makes the best mac and cheese." And then more pics of the same stuff on repeat, over and over again, each photo more underwhelming than the next.
