All of that is the fallout of an obscene video posted by the schoolgirls on YouTube.

Now experts are warning that the growing number of YouTube stunts by young Australians are destroying lives.

Three schoolgirls posted a video of themselves offering sexual acts for sale on YouTube. The offers are so explicit, the details have had to be suppressed.

The students, who are as young as fourteen, appear to revel in their very public appearance. They make no attempt to hide who they are or where they're from.

The four minute clip received almost 10,000 hits in 24 hours, before it was removed this afternoon. However other users have made several attempts to repost it. It's also a featured topic on Facebook and Twitter.

And that is precisely where the problem lies - once something is online, even if it is deleted, it can come back to haunt you.

“We're looking at the employment prospects, dating prospects, and long-term partner prospects for these girls. For the next ten or fifteen years, this can still hang around,” psychologist and social media expert Lee Hopkins said.

Filmed at a girls’ only government school in Adelaide, the students are seen sitting next to a memorial for a fellow student who was killed by an online predator.

“I think this is a failure of education,” child psychologist Michael Carr-Greg said.

“My understanding is that South Australia hasn't adopted the e-smart school system that Victoria and Queensland have adopted, and if ever there was a reason to do that, this would be it,” he added.

“They don't see the implications of their actions,” Hopkins said.

Four girls, including the student who filmed the clip, have been suspended. “Unfortunately we live in an age when something that's very simple to do, like videoing yourself and sticking it up on YouTube, can have massive consequences.”

The South Australian Education Department has released a statement saying: “the school has informed parents of the students involved in the incident,” and that “the matter was referred to the South Australian police as a precaution.”

Just last month an elite private school in Melbourne had to investigate a YouTube video showing several students sniffing a white powder. It received 200 hits online before it was removed, and while it turned out to be a prank, the school suspended three students.

Some teens go to great lengths to hoon around breaking road rules, just to get the gratification of posting the act on YouTube.

“There’s the old argument that these people want their 15 megabytes of fame, but it’s more than that. Now it is about peer acceptance and notoriety, and getting it any which way they can - the more shocking, more frightening, the more likely it is to get air play,” Hopkins said.

What many don't realise are the consequences. “I think perhaps like a lot of teenagers, they're very in touch with their own peer group, but they don't see outside of the peer group to the larger world.”

“I'd be sitting them down, to explain to them that they are still loved, that everybody is allowed to make a mistake, but there are consequences for what they have done - they are going to have to face those consequences,” Carr-Greg concluded.
