Russia’s invasion of Ukraine is the first major European land war since World War II. It is also the first fully wired conflict of the social-media era, which means there are a multitude of new ways to glean and transmit information about the militaries and governments involved. This also means there are a multitude of new ways to affect the war’s course, or at least try. Even some kid sitting in an Orlando dorm room, 5,600 miles away from Kyiv, can play a part.

An unfortunate truth about wars is that teenagers have been fighting and dying in them ever since they began, including on both sides in Ukraine today. But Jack Sweeney, a 19-year-old who attends the University of Central Florida, has found a way to contribute from the safety of the U.S. Last month, two days after missiles started flying and Russian troops crossed the border, Jack created a Twitter bot that tracks the movements of private jets owned by the country’s oligarchs—the wealthy business people surrounding President Vladimir Putin who help keep him in power and, in the process, grow even richer.
