YouTube star Logan Paul came under fire for posting a video of an apparent suicide victim in Japan’s “suicide forest,” Aokigahara.

SAN FRANCISCO — Not safe for kids. That’s the label that some parents are slapping on YouTube after vlogger Logan Paul blasted out a video of a suicide victim in the Aokigahara — the Japanese forest where dozens of bodies are discovered every year — to millions of his young followers.

“There is no filter when it comes to YouTube stars,” says Jill Murphy, editor in chief of Common Sense Media, a nonprofit organization focused on education and advocacy for kids. “It’s not until something tragic is shown via a video, and viewers react, that the content is removed or dealt with by the platform.”

“Parents need to be aware and the industry has to step up and do a better job of managing content being uploaded that people of all ages can see within seconds,” Murphy says.

Nicole Herman, a 43-year-old mom from Torrington, Connecticut, says the video was a wake-up call for her.

“My 15-year-old son came to me about this video. I was so disturbed and have not realized that I need to monitor what my son watches on YouTube,” she said. “My son was smart enough to tell me about it, which I’m extremely thankful for. I can’t…
