Julian Brown, who has amassed over 1.8 million followers for his engineering content on both TikTok and Instagram, stopped posting on July 9, 2025.
This led to concern from his followers over his well-being after Brown, 21, made a post saying he was in danger.
“I’m certainly under attack. I can’t go into so much detail,” he said in the video, where he appeared to look around worriedly.
“Something is happening, keep me in your prayers please. SCREEN RECORD THIS. I don’t know,” he captioned the clip.
In the days leading up to his posting hiatus, Brown wrote that he was working on “the most dangerous thing” he’s ever done.
He shared a video about the project on X, writing in the caption, “Grateful for my safety, let’s change the world!”
Brown is known online for his videos on making “plastoline,” or a type of fuel he claims he has been able to make using plastic waste.
According to Brown, his inventions are able to convert plastic waste into usable fuels such as gasoline, diesel, and jet fuel, with a mission to address the global plastic problem
His mission was to address the global plastic problem by creating the device that transforms plastic waste into fuel.
Just two weeks ago, the inventor posted to his YouTube channel that he and his family were “under attack right now from an extremely powerful force.”
He told his followers at the time, “I need your prayers and awareness.”
However, Brown’s mother, Nia, confirmed to The Daily Mail on July 28, 2025, that her son was safe, though she couldn’t provide more details.
“In the best interest of his security I’m not able to provide any more information,” she said.
Fans have speculated the worst after his quietness on socials, but the Atlanta Police Department confirmed they were not looking for anyone under his name.
“I can confirm that the Atlanta Police Department is not currently investigating any missing persons by that name,” police told The U.S. Sun.
In a June 2025 post, Brown claimed that a helicopter had been circling him, and asked followers to pray for him.
He also claimed that he knew he wasn’t “going to live long,” and speculated that helicopters had been following him.
Brown, the creator of NatureJab, said that he had been “falsely accused” and reported to the Internal Revenue Service and Environmental Protection Agency.
Followers flocked to the comment sections of his videos to question where the “plastoline” inventor was, with some floating around conspiracies as to where he might’ve gone.
“Where have you been,” commented one X user, while another added, “We’re all worried.”
“The work you are doing is dangerous,” another posted.
“I hope you are doing well and are safe after the last few posts you made.”
In his last Instagram video, which has almost 380,000 likes at the time of writing, Brown claimed again that he was “under attack.”
“I just want everybody to know to have their eyes open,” Brown said. “I’m just telling you guys right now: be on the lookout.”
