"So that makes it plausible to parents and school administrators".
"It's a situation where we're trying not to scaremonger the children but reinforce the message they need to be aware of what they're watching and for parents to be aware as well".
I'd encourage parents to talk with children about apps and games to better understand what they might be exposed to'.
Haslingden Primary School also cautioned that children's video clips on YouTube could be interrupted by a "warped white mask which is promoting children to do unsafe tasks without telling their parents". The game encourages the players, mostly kids, to slowly isolate and hurt themselves.
Simon Harrison, head teacher at Stubbington's Crofton School said: 'This whole situation highlights the bigger narrative of social media companies and the extent to which they can monitor their content.
It says: "The challenges issued in this game present a serious risk to the safety, welfare and wellbeing of children and young people in our schools here in the United Kingdom, as does the distressing content when a player refuses to carry on". Also, make sure you can see their screen while they are on a computer or device.
Cllr Rob Wood, Portsmouth City Council's cabinet member for Children's Social Care added: 'Keeping young people safe online is incredibly important, and with so many new apps and games being developed it can be hard to keep track of the content their children are accessing online.
A spokesperson for the NSPCC in Northern Ireland said: "The constantly evolving digital world means a steady influx of new apps and games and can be hard for parents to keep track of". We talked to them about what to be cautious about online.More news: It’s your turn to get ready for surprise, Pakistan Army tells India

"These video clips are appearing on many social media sites and YouTube (including Kids YouTube)".
Ms Dixon added that her son initially refused to go upstairs because it was dark and wouldn't even sleep in his own bed. It is believed to either be created as a scam to extract personal information or as an urban legend type hoax, and is based on a meme of a sculpture.
The second NOS recommendation is for parents or carers to be present while the children are online.
Instagram says it has now deleted three accounts involved in promoting "Momo".
The first thing the NOS recommends parents do is tell the children that Momo isn't real.
"She knew how to show me (the video) straight away".
'Honey said she'd never watched a video of this sick freak telling her to do bad or risky things but that she's popped up in loads of innocent kids videos on YouTube, where her neck twists round or she'll walk across the screen! She said that Momo was sending codes to people and the codes translated to the word 'die.' It wasn't clear if Momo was sending the codes to other characters. So I have one very frightened little boy and some deep concerns about the kids in his school. Normally she would watch it through her phone or Xbox. "This is one of the most disturbing things I have ever heard", he said in an email to Eyewitness News.
