Last spring, Michael McAllister’s inbox started filling up with messages from heartbroken women. “I thought you were the man,” one wrote. “Embarrassing, but I kinda became obsessed with ‘you,’” another said. Michael discovered that his photos were being used to catfish women on dating apps — from Germany to Brazil to Chicago. Today’s story explores a global dating scam (that’s still going on, by the way) and the pandemic-fueled loneliness of digital life. Also, we hear from two women who were duped by Michael’s impostor. One of them shares a trick for determining whether or not a dating prospect is real.
