Elon Musk says a 'crazy stalker' climbed onto a car carrying his son X Æ A-12

Elon Musk has revealed a 'crazy stalker' followed a car carrying his son X Æ A-12.

The Tesla CEO tweeted to his followers: “Last night, car carrying lil X in LA was followed by crazy stalker (thinking it was me), who later blocked car from moving & climbed onto hood.

“Legal action is being taken against [Jack] Sweeney & organizations who supported harm to my family.”

He also wrote: "Any account doxxing real-time location info of anyone will be suspended, as it is a physical safety violation. This includes posting links to sites with real-time location info.

"Posting locations someone traveled to on a slightly delayed basis isn’t a safety problem, so is ok."

For those of you unaware of who Sweeney is, he’s the 20-year-old who has been tracking the movements of Musk's private jets.

Sweeney has been using publicly available information to reveal all the journeys made by the tech billionaire's plane and he's been posting them on the Twitter account @ElonJet.

Twitter recently 'shadow-banned’ Sweeney’s account.

For those unfamiliar with 'shadow-banning', it's when a user is restricted access to their account without being booted off the platform entirely.

On December 14, Sweeney's account was suspended, along with his personal account.

Jack slammed the Twitter CEO over the move.

He told The New York Post: “This is insane. My phone’s going f**king nuts.”

Musk allowed Sweeney to keep operating his page when he took over the social media company in October under the guise of freedom of speech.

"My commitment to free speech extends even to not banning the account following my plane, even though that is a direct personal safety risk," Musk wrote on November 7.

However, Sweeney called the 51-year-old a ‘hypocrite’ for reversing his decision.

“He really is asking for it because it’s just going to get worse in the news,” he said.

The Twitter account tracking Musk's plane was momentarily reinstated before being suspended again.

Social media was conflicted in the wake of Sweeney's suspension.

One user said: "But you promised! And he claims that it's platform manipulation."

Another added: "Yeah, this was a huge security issue. It’s important that you did this."

Others pointed out Sweeney was just using data that anyone could access.

One person tweeted: "The information is publicly available already so it isn't doxxing."

Another said: "[But] the flight data that was being used was delayed and not real-time information."

Twitter has now updated its policy on location tracking.

The new rules state: "You may not publish or post other people's private information without their express authorization and permission.

"We also prohibit threatening to expose private information or incentivizing others to do so.

"In addition, you may not share private media, such as images or videos of private individuals, without their consent.

"However, we recognise that there are instances where users may share images or videos of private individuals, who are not public figures, as part of a newsworthy event or to further public discourse on issues or events of public interest.

"In such cases, we may allow the media to remain on the platform.
