Jack Sweeney, 19, created a Twitter account called "Russian Oligarch Jets" in February amid President Vladimir Putin's invasion of Ukraine.

The account tracks the movements of some of Russia's wealthiest businessmen, informing account followers of when and where their aircrafts take off and land along with a short summary of flight information, such as the location and duration of each trip.

The automated feed posted its first tweet on Sunday, the same day that the United States sanctioned two of Russia's state-owned banks, the country's sovereign debt, and elites with close ties to Putin.

Prior to the Biden administration's sanctions, German Chancellor Olaf Sholz announced a freeze on the Nord Stream 2 pipeline, which would carry 55 billion cubic meters of natural gas from Russia to Germany each year.

Subsequent "massive and targeted" sanctions against Russia were also announced by the EU, which focused on the country's oil, financial, transport, and energy sector, and visa policy which targets Russian oligarchs.

Yet despite multiple sanctions from the West meant to financially cripple Russia's elite, Sweeney's account shows that many of them are still jet-setting across the globe in private planes.

So far, Sweeney's account is tracking the Russian billionaire and businessman Roman Abramovich; a former scientist turned industrial magnate, Alexander Abramov; and the president of aluminum manufacturing giant Rusal, Oleg Deripaska.
