A Swedish court is looking into one of the strangest file-sharing cases we've ever heard of. With a Pirate Bay username as the prime evidence, a Swedish man is suspected of distributing a film about moose hunting. The filmmaker, who hunted down the alleged infringer by himself, is demanding $15,000 to compensate his losses.

Tor Lundberg, the maker of ‘Löshundsjakt i norr’ was furious when he found out that his film could be downloaded for free on The Pirate Bay and other torrent sites. Instead of going to the police directly, he took the matter into his own hands.

Lundberg called in a friend who assisted him with his investigation, and they eventually managed to track down the person who allegedly uploaded the torrent file based on his Pirate Bay username.

The username of the uploader apparently gave away enough information to link it directly to a real life person, a man in his thirties, also a Swedish resident. The filmmaker and his partner Lars Öderyd then decided to contact the alleged uploader to confront him with his actions.

What was said exactly during that phone conversation remains unclear, but for the maker of the film it was enough to get the police involved. Without much technical evidence the case is now under review by the court, where Tor Lundberg has demanded $15,000 as compensation for his losses.

The Pirate Bay user in question admitted that the torrent was uploaded through his account but denied that he was the one who distributed the film. He later told the police that someone might have used his account to publish it, but that he himself didn’t even own a copy of the film.

The case in itself is quite unique since the only evidence in the case seems to be a Pirate bay username, the torrent itself can no longer be found on The Pirate Bay. Despite the lack of technical evidence, prosecutor Henry Rasmusson is confident that he can get a conviction out of it.

Filmmaker Tor Lundberg claims that the Pirate Bay user ‘destroyed’ him and feels that he is entitled to be compensated for the claimed losses.

“It’s another thing to share Madonna’s work, who is multi-millionaire. Or Apple products, for example. But when you make something yourself, it’s your own money you have invested in it. So the effects are much more severe for an individual,” he said.
