Web 2.0 and communities online include the seed to their own destruction, as was proved recently when a teenager forced YouTube to pull hundreds of video clips from its servers. YouTube shouldn't fear the media giants, it should be scared of its own users.

A 15-year-old Ozzie pretended to be an employee of ABC, the Australian Broadcasting Corporation.

Funnily enough, the most annoyed group wasn't YouTube or its many users who got stern letters reminding them of copyright violation laws. It was ABC itself whose lawyers gave the teen a stiff telling off.

ABC's head of TV comedy, Courtney Gibson, said: "Everyone does dumb stuff when they are 15. We really appreciate that he's apologised and we'll be following up with him next week."

"What was of concern to us was the fact that YouTube was sending copyright infringement notices to people who have been uploading our clips to YouTube, threatening to shut down their access to YouTube if they persist. That's what was worrying to us."

So anyone can upload clips of ABC shows to the Internet with impunity, it seems. In fact, ABC would be terrified if no one was using its content for their own purposes.

In October, YouTube deleted 29,549 copyright-violating files after pressure from the Japan Society for Rights of Authors, Composers and Publishers.

A month later Google CEO Eric Schmidt denied that his company had set aside $500m to settle copyright claims by media companies against YouTube.

Looks like that half a billion is pretty safe if ABC's actions make any sense, which - as hard as I try to explain - they do not.
