(CNN) - Most parents feel pretty safe letting their children watch YouTube Kids, the child-friendly version of the video platform.But disturbing videos recently found by some moms show the social media site may not be safe for kids at all.A Florida mother said she has found clips on YouTube and YouTube Kids that gave children instructions on how to kill themselves.Free Hess said the first time she saw such a video was back in July when another mom alerted her to it after she and her son were watching cartoon videos on YouTube Kids. Spliced in the middle of one of the videos was footage of a man in sunglasses telling children how to slit their wrists.Hess, a pediatrician, put out a call to action to different groups to report the video to get it removed from the site. Hess said it took YouTube Kids a week to pull it down.What she saw shocked herBut this month she saw the video again, this time on YouTube. Once again, after the video was flagged by her and others, it took a couple of days for YouTube to pull it, said Hess, who has been writing about the issue on her parenting blog."It makes me angry and sad and frustrated," Hess told CNN. "I'm a pediatrician, and I'm seeing more and more kids coming in with self harm and suicide attempts. I don't doubt that social media and things such as this is contributing."But that's not all she said she found. When Hess went to YouTube Kids and started exploring the site, what she saw there shocked her. She said she found videos glorifying not only suicide but sexual exploitation and abuse, human trafficking, gun violence and domestic violence. One video, inspired by the popular "Minecraft" video game, even depicted a school shooting."There were just so many that I had to stop recording," she said.Hess wants YouTube to do a better job of screening videos intended for YouTube Kids. She said she understands that Google (which owns YouTube) is a business and "they might not have the exact goals that I have, but I do want them to respond better when people report offensive videos, and I want offensive things taken down immediately when reported."In response to Hess' allegations, YouTube said in a statement that it works to make the videos on YouTube Kids family-friendly and takes feedback seriously."We appreciate people drawing problematic content to our attention, and make it possible for anyone to flag a video," the statement said. "Flagged videos are manually reviewed 24/7 and any videos that don't belong in the app are removed."We've also been investing in new controls for parents including the ability to hand pick videos and channels in the app. We are making constant improvements to our systems and recognize there's more work to do."She says parents need to step upHess did say that YouTube is faster about pulling questionable videos from YouTube Kids than from regular YouTube. But she thinks by the time someone reports something, it could have already caused harm."Once someone reports it, it's too late because a kid has already seen it," she said.Hess also wants parents to be more aware of what their children are watching on YouTube and YouTube Kids, and for parents to do a better job in general of keeping up with technology."There is this disconnect between what kids know about technology and what their parents know because the parents didn't grow up with it," she said. "The kids are the digital natives and the parents are digital immigrants."Most importantly, she says, parents need to team up with each other to combat this problem."We need to fix this," she said, "and we all need to fix this together." 3617

(KGTV) - A San Bernardino County woman is suing the California Department of Fish and Wildlife and state Natural Resources Agency for not acknowledging the existence of Bigfoot.Claudia Ackley told The Press-Enterprise she ran into the long-fabled creature while hiking in Lake Arrowhead last year. Ackely said she was hiking late one March day when she and her two daughters ran into a Sasquatch."I ran into a Sasquatch – a Bigfoot. We were face to face. He was 30 feet up in the tree," Akley told the paper. "He looked like a Neanderthal man with hair all over him. He had solid black eyes. He had no expression on his face at all. He did not show his teeth. He just stared at the three of us."Ackley said her daughter told her she saw two other creatures run away following the encounter, adding that her daughter captured the encounter on video - which Press-Enterprise published online."People have to be warned about these things. They are big," Ackley said. "We’re totally vulnerable to these things."The lawsuit, filed on Jan. 18, alleges the state departments of failing to acknowledge the existence of the Sasquatch species, despite documented and scientific evidence, according to Press-Enterprise. 1256
