NOTORIOUS internet troll Tristan Barker's online army has struck again - this time duping Today Tonight into running a bogus story.

Channel 7 branded Barker "the world's nastiest man" on Monday night when Today Tonight ran a lead exposé into his online behaviour of harassment and ridicule.

During the story Barker was interviewed dressed in full Nazi regalia.

As part of the 10 minute story, Today Tonight interviewed supposed cyber bully victim Jasmine Vanmidde, who last night went under the name "Jasmine Frost".

The teenager complained of cyber-bullying and harassment at the hands of Barker's "Facebeef" Facebook page. She claimed to have received pornographic images from Barker and his posse.

"It's just like anything, if you sit in silence, nothing's going to be done," she said on the current affairs program, explaining why she was appearing.

It is understood Melbourne-based Vanmidde approached Today Tonight last week when she learned the show was preparing a story about Barker and asked to be interviewed.

But everything fell to pieces last night when it emerged Vanmidde was in fact a member of Barker's online trolling community and was spruiking a fictitious story to reporter David Eccleston.

In a YouTube video posted a few hours after the Today Tonight show aired, she boasted:

"All it took was an email entitled ‘Tristan Barker cyber bullied me' and then a three minute phone call to convince one of the most watched and believed news programs in Australia that I was a poor bullied girl, when in reality I'm a member of the Facebeef team and have been so for the better part of a year."

The video had accumulated in excess of 70,000 YouTube views this morning.

Vanmidde posted on Facebook shortly after the program: "If I was Today Tonight, I would be feeling a little bit silly right now".

The apparent sleight of hand has been met with praise and adoration from Barker's loyal network of fans, with Vanmidde's revelation garnering nearly 4000 "likes" and over 70 thousand Youtube views.

At the end of the video she kisses Lewis Spears aka "Nebz Adlay" – Barker's chief offsider who is temporarily fronting his social media claiming Barker has been restricted from speaking publicly – on the lips.

It is believed Vanmidde and Spears are romantically linked.

Today Tonight executive producer John Choueifate told News Ltd the show was not made aware of the young lady's identity until after it aired.

"She's nothing more than an attention seeker," he said. "We took her at face value and went to every measure to ensure her story stacked up, as we do with every guest.

"We found evidence to suggest that she had been bullied by Tristan Barker…when people are using fake names it gets very difficult to control.""

He confirmed Today Tonight would be running a correction this evening.
