The Jayden K. Smith Facebook Hoax refers to a viral chain letter that spread rapidly across Facebook in mid-2017. The message warned users not to accept a friend request from a supposed hacker named Jayden K. Smith, claiming that doing so would allow him to hack the user's account and their entire contact list. Like many hacker hoaxes before it, the warning was entirely baseless and served only as a nuisance that cluttered newsfeeds. The meme evolved as a way to satirize the technological illiteracy of users—often older demographics—who reflexively share alarmist warnings without verification. Today, the name Jayden K. Smith has become shorthand for the harmless yet annoying nature of social media misinformation and the fear-mongering chain letters of the late 2010s.
