Sopa: Sites go dark as part of anti-piracy law protests

Thousands of internet sites are taking part in a "blackout" protest against anti-piracy laws being discussed by US lawmakers.

The Wikipedia encyclopedia and blogging service WordPress are among the highest profile pages to remove material.

Google is showing solidarity by placing a black box over its logo when US-based users visit its site.

The Motion Picture Association of America has branded the action as "irresponsible" and a "stunt".

Visitors to Wikipedia's English-language site are greeted by a dark page with white text that says: "Imagine a world without free knowledge... The US Congress is considering legislation that could fatally damage the free and open internet. For 24 hours, to raise awareness, we are blacking out Wikipedia."

It provides a link to more details about the House of Representatives' Stop Online Piracy Act (Sopa) and the Senate's Protect Intellectual Property Act (Pipa).

If users try to access its other pages via search sites, the text briefly flashes up before being replaced by the protest page. However, people have been sharing workarounds to disable the redirect.
Global protest

WordPress's homepage displays a video which claims that Sopa "breaks the internet" and asks users to add their name to a petition asking Congress to stop the bill.

"The authors of the legislation don't seem to really understand how the internet works," the site's co-founder, Matt Mullenweg told the BBC.

Across the globe, several Pirate Party sites have been taken offline. The political parties - which advocate reform of copyright laws - took the action in the UK, Spain, Sweden, Argentina, Canada and elsewhere.

Google posted a blog on the subject claiming that the bills would not stop piracy.

"Pirate sites would just change their addresses in order to continue their criminal activities," it said.

"There are better ways to address piracy than to ask US companies to censor the internet. The foreign rogue sites are in it for the money, and we believe the best way to shut them down is to cut off their sources of funding."

Other net firms that have criticised the legislation decided not to take part in the blackout.

Twitter's founder, Dick Costolo, tweeted that it would be "foolish" to take the service offline.
