The year-old social media platform, owned by Meta, on Monday abruptly suspended an account showing flight paths of the private jet owned by Mark Zuckerberg, CEO and co-founder of Meta, along with several other accounts showing similar data for the private jet use of Elon Musk, Jeff Bezos, Bill Gates, Kim Kardashian, and Kylie Jenner. On Friday, an account tracking Taylor Swift’s jet was also suspended.

All of the accounts were maintained by Jack Sweeney, a college student who gained some public notoriety when Musk took over Twitter in 2022 and banned the same kind of jet tracker accounts, including the one Sweeney had tracking Musk’s own jet. Sweeney eventually moved much his jet tracking activity to Threads after the dispute with Musk.

Posting to Threads from his personal account, Sweeney said that all of the jet tracker accounts he maintained on the Meta platform were suspended over the past few days, save for two: one following the jet used by former president Donald Trump and one following the jet used by Florida Governor Ron DeSantis.

“Quite strange,” Sweeney added. Not long after, the Trump and DeSantis jet accounts were also suspended.

Although all of the private jet data displayed in Sweeney’s Threads accounts is publicly available and maintained by the U.S. Federal Aviation Administration, the sharing of the information over social media has raised the ire of many of the celebrity jet owners, who complain that it infringes on their privacy.

Musk and Swift, although opposed politically, have both threatened Sweeney with lawsuits, referring to the jet accounts as “assassination coordinates” (Musk) and “stalking and harassing behavior” (Swift).

Sweeney’s accounts do not show exactly where the planes or their occupants travel. Neither Musk nor Swift have taken formal legal action against him.

In a text message with Fortune, Sweeney said he had recieved “zero” explanation or opportunity to appeal. “If I log in it’s just black.”

A representative of Meta did not respond to an email seeking comment.
