Jack Sweeney, the person behind the jet tracking account, ElonJet, took to Twitter on Sunday to accuse the social media platform of suppressing the automated account.

In a thread Sweeney dubbed, "My Twitter Files," he claimed an anonymous Twitter employee informed him that his ElonJet account was "visibility limited/restricted to a severe degree internally" on December 2.

He also shared what appeared to be an internal Twitter message from Ella Irwin, Twitter's new head of Trust and Safety, requesting that ElonJet be subjected to "heavy VF [visibility filtering].

Sweeney told Insider that he'd suspected "for quite a while" that "@ElonJet was definitely search banned/ search suggestion banned" before the supposed Twitter employee contacted him.

Insider has not been able to independently verify Sweeney's claims.

Shadowbanning generally makes a user's profile and posts more difficult to find without alerting the user. Some users had already claimed that they couldn't search or tag the jet tracking account through suggested usernames.

Musk has previously publicly criticized the practice of shadowbanning and said that Twitter is working on a feature that will clearly show users when they've been shadowbanned.

The Tesla CEO has taken issue with the jet-tracking account before, accusing it of being a security risk and once offering to buy it. Sweeney operates more than 30 plane-tracking accounts that share publicly available data. Many of the accounts track billionaires, including Meta CEO Mark Zuckerberg, Amazon founder Jeff Bezos, and Microsoft's Bill Gates.
