This week, MPAA chief and former U.S. Senator Chris Dodd praised pirate site blockades as an important anti-piracy measure. Speaking at the IP Summit in London, Dodd said that ISP blockades are one of the most effective tools available. Does this mean that Hollywood will try to get these blacklists in place on its home turf?

This week many key figures in the copyright protection and enforcement industries gathered for the International IP Enforcement Summit, organized by the UK Government.

One of the main topics of discussion was Internet piracy, and how to prevent people from accessing and sharing copyrighted works without permission.

Website blocking is one of the anti-piracy tools that was mentioned frequently . In recent years the UK has become a leader on this front, with the High Court ordering local ISPs to block access to dozens of popular file-sharing sites, including The Pirate Bay and KickassTorrents.

MPAA chief Chris Dodd, who delivered a speech at the Summit, applauded the UK approach. The former U.S. Senator believes that these restrictions are helping to decrease the piracy problem.

“Here in the United Kingdom, the balanced and proportionate use of civil procedures has made tremendous progress in tackling infringing websites. To date, access to over 40 pirate sites focused on infringing copyright for commercial gain, have been blocked,” Dodd said.

According to Dodd these blockades have proven to be one of the most effective anti-piracy measures in the world, made possible by a provision in local copyright law.

“In particular, Section 97A of the Copyright Act allowing courts to issue injunctions against service providers who know their services are being utilized for infringing purposes, has been one of the most effective tools anywhere in the world,” Dodd says.

Despite the MPAA’s faith in website blockades, which is not shared by everyone, the movie group has never attempted to ask a U.S. court for a similar injunction. This is surprising since nearly all the sites that are blocked in the UK have far more users from the United States.

TorrentFreak asked the MPAA to explain this lack of action, but we have yet to hear back from them.

Previously we spoke to an insider who admitted that these type of ISP blockades are harder to get in place under United States law, which is one of the reasons why the copyright holders haven’t tried this yet.

The issue became even more complicated after the copyright holders’ push for SOPA failed early 2012. In part, SOPA was designed to give copyright holders a shortcut to request injunctions against pirate sites.

Putting the law aside, the MPAA has made it clear that it’s keen on maintaining good relationships with the Internet providers. ISPs and copyright holders are taking part in a voluntary agreement to “alert” pirates, which will undoubtedly be harmed if additional blocking demands appear on the table.

For now, it seems that the MPAA and other industry groups will continue to press for more voluntary deals in the U.S. Interestingly, Dodd specifically calls for a cooperation with search engines to indirectly block pirate sites, instead of asking for a more direct blockade from ISPs.

“If we convince these search engines to join our efforts to shut down illegal sites, it would be a significant step forward in our ongoing efforts to protect creators,” he said.

Thus far Google and other search engines have refused to remove pirate sites from their search indexes. Also, one has to wonder how effective that would be. Thus far Google has removed more than two million pages from The Pirate Bay, but the site’s traffic continues to expand regardless.

But then again, even an ISP blockade is easy to circumvent, and perhaps not as effective as the MPAA claims.
