FELINE WEB PRESERVER The Internet Defense League (IDL) said that 9.2 million people and thousands of websites joined its protest against illegal government surveillance.
The IDL, which has a natty cat symbol, lead the protests, and asked people to show up and protest and for websites to display a message against the US National Security Agency (NSA) PRISM programme and government snooping.
"In the wake of shocking revelations about sweeping NSA surveillance, the Internet Defense League - a coalition of thousands of websites that formed after the Internet Blackout against SOPA - and hundreds of sites, organizations and internet users have organized the largest online protest since the SOPA blackout," it said.
"Thousands of people attended Restore the 4th street actions that happened around the country and tens of thousands more rallied on the web calling for an end to unconstitutional government spying."
The IDL was joined in its campaign by grassroots groups, individuals, and high level technology leaders and businesses.
Lining up to oppose the NSA were Reddit, 4chan, Mozilla, O'Reilly Media and the Electronic Frontier Foundation.
The campaign is backed with an advert embedded below that says spying on US citizens is unconstitutional and should be stopped. The theme of this message was repeated on supporting websites like Reddit and through Mozilla's Twitter account.
"The US Government has been systematically spying on people all over the globe, violating their human rights," said Tiffiniy Cheng of the Internet Defense League and Fight for the Future.
"The NSA [programmes] that have been exposed are blatantly unconstitutional, and have a detrimental effect on free speech and freedom of press worldwide. This is going to be our biggest protest since SOPA, and it should be no surprise. You can't disregard people's privacy, invade their personal lives on a daily basis, and not expect them to fight back." µ
