Twitter on Wednesday suspended more than 25 accounts that track the planes of government agencies, billionaires and high-profile individuals — including one that followed the movements of the social media company’s owner, Elon Musk, who has said he was committed to “free speech.”
Jack Sweeney, a 20-year-old college student and flight tracking enthusiast, said he woke up on Wednesday to find that his automated Twitter account, @ElonJet, had been suspended. In recent months, the account amassed more than 500,000 followers by using public flight information and data to post the whereabouts of Mr. Musk’s private plane.
Mr. Musk had been aware of @ElonJet for months. After buying Twitter for $44 billion in October, he said that he would allow the account to remain on the platform. “My commitment to free speech extends even to not banning the account following my plane, even though that is a direct personal safety risk,” Mr. Musk tweeted last month.
Mr. Sweeney’s personal Twitter account was also suspended on Wednesday, along with the other accounts that he runs that track the planes of tech billionaires such as Mark Zuckerberg, Jeff Bezos and Bill Gates. Mr. Sweeney shared a message that he had received from Twitter, which said his account had been suspended for violating rules “against platform manipulations and spam.”
In an interview, Mr. Sweeney said he had not changed how the plane tracking accounts behave and was given no specific reason that they had been suspended. “He’s doing the exact opposite of what he said,” he said of Mr. Musk, adding that the suspensions felt arbitrary given that the accounts had existed for months.
Since taking over Twitter, Mr. Musk has gone back and forth on deciding what content and accounts should and should not be on the platform. He initially said he would form a council to make decisions on content moderation but then abandoned those plans. He also welcomed back the account of former President Donald J. Trump and declared an amnesty for people, including white nationalists, who had been suspended from Twitter for violating its rules on hate speech or incitement to violence.
Mr. Musk and Twitter did not respond to a request for comment.
Before he owned Twitter, Mr. Musk offered Mr. Sweeney $5,000 to take @ElonJet off-line; he later blocked the student after Mr. Sweeney tried to negotiate. Mr. Sweeney has since created more than two dozen automated Twitter accounts using public flight data to track the planes of tech billionaires, Russian oligarchs and national and international government agencies.
Jason Calacanis, a tech investor and an adviser to Mr. Musk for the Twitter takeover, tweeted on Wednesday that his personal belief was that “sustained sharing of public location information is de facto doxing,” using a phrase typically reserved for the sharing of private information on the internet.
Mr. Sweeney said that the information shared on the accounts was already public.
“If someone wanted to do something, they could do it without me,” he said.
