Billionaire businessman and entrepreneur Elon Musk recently purchased 420 private jets in an effort to prevent 19-year-old college freshman Jack Sweeny from using an algorithm he created to reveal where Musk and his plane are at all times.

Notably, Musk had initially direct messaged Sweeny on Twitter asking him if he’d take $5,000 to stop what he was doing. The teen turned him down, instead asking for $50,000.

“I may have spent $25 billion just to run decoy flights around the globe, but now that little shit will have no idea where I really am,” a grinning Musk told reporters. “Worth. Every. Penny.”
