The folks behind Pirate Bay are upset over a new Web site from antipiracy group CIAPC that looks just like their own site.

To kick off its latest antipiracy campaign, the Finland-based CIAPC (Copyright Information and Anti-Piracy Center) set up a new Web site urging people to find more legal means to download music, TV shows, and other digital content. To hammer home its point, the CIAPC site intentionally borrowed the exact design and style of the Pirate Bay site.

The group even duplicated the CSS stylesheet used by the Pirate Bay, ensuring that its site is a virtual duplicate, according to torrent news site TorrentFreak. The only difference is that the CIAPC's site shows an image of a sinking ship in contrast to the floating pirate ship that marks the Pirate Bay site.

But the move may land the CIAPC in hot water.

"We are outraged by this behavior," a Pirate Bay spokesman told TorrentFreak. "People must understand what is right and wrong. Stealing material like this on the Internet is a threat to economies worldwide. We feel that we must make a statement and therefore we will sue them for copyright infringement."

The Pirate Bay's usage policy states that organizations can use the system only if they first get permission from the system operators, something the CIAPC obviously didn't do. As such, the site imposes a fine on any group that violates the terms.

"We reserve the rights to charge for usage of the site in case this policy is violated," the policy states. "The charge will consist of a basic fee of EUR 5,000 ($6,663) plus bandwidth and other costs that may arise due to the violation."

The CIAPC isn't likely to pay the fine, so the Pirate Bay could try to take the group to court.

The Pirate Bay itself is no stranger to lawsuits. Its site provides links to torrents, allowing people to freely download music, TV shows, movies, and apps. As such, it's gotten into legal skirmishes over copyright infringement. But the site somehow has a way of staying alive.

In February 2012, the Pirate Bay stopped hosting torrents directly and instead became more of a search engine for people to download files from other torrent sites.

A spokesman for the CIAPC told CNET that it hopes "the operators of the Pirate Bay site come out publicly with their true identities and get in touch with the CIAPC."

CNET contacted the Pirate Bay for comment and will update the story if we receive any information.
