Who is to blame for Chinese rooftopper's dramatic death?

Photos posted to Wu's Weibo social media account in early November, shortly before his death.

(CNN)A video circulating on Chinese social media shows a young man preforming chin ups while hanging from the side of a 62-story building in the city of Changsha -- no safety harness, no ropes, nothing.

As the film continues, he struggles to pull himself back up onto the roof, as he's done many times before in dozens of videos. He pauses for a moment, looks down and then falls.
Wu Yongjing, whose nickname on Chinese social media was "the Extreme," is a casualty of the international daredevil trend known as "rooftopping," which has taken off across China where a ready prevalence of newly built skyscrapers has combined with a boom in social media apps.
    Photos posted to Wu's Weibo account in September and October 2017.
    In response to Wu's death on November 8, an editorial in state media China Daily called for greater supervision of livestreaming apps in China.
    "Had Wu not been so popular on livestreaming apps, he might not have died ... Some of them try to hype things up with obscene and dangerous things, and their purpose is to attract more eyeballs and make a profit. It is time we ended this," the article published on Tuesday said.
    Not everyone does extreme stunts on the very edge of buildings. Some rooftoppers just like to take photos from stunningly tall, often newly constructed buildings, which they often enter without permission, but others like 26-year-old Wu take things a step further.
    His previous videos show him hanging off the edge of glistening skyscrapers supported by just his hands. Sometimes he does pull ups.
    But Chinese rooftopper Claire, who asked us to not to reveal her last name, told CNN she doesn't just blame Wu's risk-taking for his death -- instead, she says the companies who sponsor rooftoppers are also to blame.
    "These companies will pay money to the video-makers," she said, if the rooftoppers will allow that company to advertise on their videos.
    "If you sign a contract with them, they'll pay for your tickets and accommodation and everything to fly you to another city to do crazy things. And they state clearly that they are not responsible for any casualties if there ever was one."
