AN APP wildly popular with kids can today be exposed as being a "haven for groomers" where children are subjected to sick porn threats and told to take their clothes off.

Bigo Live allows users to broadcast to thousands using their phone's camera and microphone - with anyone able to view their footage.

While bosses at the app - which boasts two million followers on Facebook - say that users have to be over 16 to use it, there are no genuine identity checks with the free and easy sign up process.

And The Sun Online has encountered dozens of British children under the age of 16 broadcasting to strangers who make vile comments and demands while the kids address the camera.

One young girl is told: "You need to get tied up and raped badly to death"

A user going by the name Bigd*** told a child: "Lift top up a bit?"

Another young girl is asked: "Wanna see more of me in knickers x wanna see my six pack x."

And during an early morning broadcast, a young boy lying in bed is told by two different users: "Hi sexy", "Show full body", "Show down pls", "Moreeeeeeee".

We have also witnessed the app being used as a way of targeting children with sick threats.

A young boy broadcasting at home was set upon by an older man, who had been viewing his profile which featured family photos.

The man tells the boy: "Ask anyone on Bigo how I work. I get their f****** details like address... I work by address b****. I work with the miles and the distance."

A parent then gets involved during the exchange, and can be heard saying: "Oh my God."

The man then adds: "Mhmm. Just remember that. You know those innocent little kids are going to be edited?

"Pornography.... I'm a sick mother f****** aren't I? I'm a sick mother f******."

A voice from the young boy's broadcast replies: "You are a sick f*****. You're right there."

He responds: "Thank you. Thank you. Oi oi tell [name removed] if I put her step dad with a child sh******* the kid how is it going to look?

"Not like a f******* random child... it's going to be her own blood."

The conversation is then ended.

Each time The Sun Online encountered a situation where a child was featured or being sent inappropriate messages, the users - both the child for being underage, and the perverts sending the messages - were reported to moderators who claim to monitor broadcasts "24/7".

Many child accounts remain active however, and those sending inappropriate and sexual messages remain unbanned.

Bigo Live, which is based in Singapore, even boasts to users in a bid to get them to upgrade their app to the latest version: "The new version allows you to appeal unban automatically."

A concerned user who became aware of the app when it was advertised on Facebook told The Sun Online: "It's a haven for groomers.

"Anyone can sign up, there's kids on it all the time and sexual predators are demanding they remove clothes or making threats.

"When I've seen this sort of stuff, I have reported it to the moderators but nothing is ever done.

"They claim that streams are monitored 24 hours to stop this kind of thing, but that clearly isn't happening and it's about time people are aware of what's going on here."

In online reviews of the app, concerned users have voiced worry about how many children are using it and how they are being preyed upon.

One said: "I only used this app for one day and in just a few hours you get to know that people in this world are so sick and so paedophilic they do not even care a bit about the child."

Another wrote: "The most vile, disgusting and perverted app I've ever come across. On three occasions three [users] were m*********** on screen, hiding their faces and saying 'I love you' to teenage girls.

The Sun Online has approached Bigo Live for comment but has not received a response.

Facebook has also been contacted to clarify if it will continue to advertise the app on its platform, but a spokesman declined to comment.

The NSPCC Associate Head of Online Safety, Laura Randall, said: “Livestreaming apps like Bigo are a magnet for young people, offering the opportunity to communicate with others in a new and exciting way.

“Unfortunately there is a much darker side to these social networks, with adults also using them to groom children and commit horrendous acts of sexual abuse.

“To stamp this out, and bring an end to the Wild West Web, tech firms need to be held to account and forced to design much stronger protections for the young people who use their platforms.

“This can only be achieved by the Government stepping in and introducing robust and effective regulation, something we are campaigning hard to see happen.”
