Jack Sweeney, 21, is a computer science student at the University of Central Florida. He uses bots to track the flights of celebrities online, including Mark Zuckerberg, Jeff Bezos, Kim Kardashian and Donald Trump.
He has already quarreled with the richest man in the world, Elon Musk, because of exactly this tracking. Sweeney is now active again on X, but all information about Musk's flights only appears with an artificial time delay of at least 24 hours, via an account called ElonJetNextDay.
