BTJunkie, a popular file-sharing indexing site, said Monday it was voluntarily shutting down, less than three weeks after the U.S. closure of Megaupload in a crackdown on piracy of music, films and other materials.

"This is the end of the line my friends," BTJunkie said in a brief message posted on the home page of the site along with the dates of its existence: "2005-2012."

Google Doodle, which highlights anniversaries on the Google search engine, Monday showcased Francois Truffaut, the late French "new wave" film-maker who would have turned 80 on Monday.

Truffaut, who died of cancer at age 52, notably directed the films "the 400 blows" (1959), "Jules and Jim" (1962), and "The last metro" (1980) which Google Doodle illustrators chose to remember on the search engine's homepage.

Online giants Google and Facebook said Monday they had removed allegedly offensive content on their Indian sites as part of a court case seen as a test for Internet control and censorship.

Twitter said users were firing off a record 10,000 tweets per second in the final three minutes of the Super Bowl.

CyberForce used Twitter to claim responsibility, saying "We have succeeded in the attack against the government."

For most people, that word means something malicious — shady criminals who listen in on private voicemails, or anonymous villains who cripple websites and break into email accounts.

A new not-for-profit media group was launched in Australia Monday entirely funded by a philanthropist who has pumped Aus$15 million into a start-up that promises "fearless, independent" journalism.

The online Global Mail will be operating in an environment dominated by Fairfax and Rupert Murdoch's News Limited but is confident it can carve a niche.

Controversial tweets by a Khmer Rouge tribunal judge have inflamed a damaging public spat between the U.N. and Cambodia and raised questions over how Twitter is used in the courts.

Poland's prime minister said Friday that Warsaw would put on ice plans to ratify a controversial international online anti-piracy accord after massive off-and-online protests in his country.

"I consider that the arguments for a halt to the ratification process are justified," Donald Tusk told reporters.

Trading jokes and swapping leads, investigators from the FBI and Scotland Yard spent the conference call strategizing about how to bring down the hacking collective known as Anonymous, responsible for a string of embarrassing attacks across the Internet.

Unfortunately for the cyber sleuths, the hackers were in on the call too — and now so is the rest of the world.
