An anonymous Wikipedia user from an IP address that is registered to United States Senate has tried, and failed, to remove a phrase with the word "torture" from the website's article on the Senate Intelligence Committee's blockbuster CIA torture report.

The unknown individual has attempted on at least two occasions — first on Dec. 9 and then on Dec. 10 — to remove a line describing the CIA's enhanced interrogation techniques as "a euphemism for torture."

In both instances the anonymous editor explained that he or she was "removing bias" from the article. And each time the revision was overruled.

The debate over the classification of "torture" for the CIA's techniques has played out in the halls of Congress, on Sunday talk shows and behind closed doors. Wikipedia appears to be the latest battleground over public opinion as many, now, ponder the legalities of some of the more aggressive techniques used by CIA officers during the decade-long war on terror.

The United Nations, joined by a number of human rights groups, have called for the prosecution of U.S. officials who were responsible for the CIA torture program.

"It is now time to take action," said UN Special Rapporteur on Human Rights and Counter-Terrorism Ben Emmerson in a statement. "The individuals responsible for the criminal conspiracy revealed in today’s report must be brought to justice, and must face criminal penalties commensurate with the gravity of their crimes."

"By choosing to move on, to forget about the past, not to prosecute the serious crime, Obama is keeping torture as a misguided, wrongful policy option for some future American president," added Kenneth Roth, Executive Director of Human Rights Watch, on Wednesday.

The Wikipedia revelations came to light on Tuesday and Wednesday thanks to a Twitter bot that tweets anonymous edits that are made from IP addresses in the US Congress.

That account, @congressedits, has been around since July 2014 and has alerted followers nearly 430 times of covert Wikipedia changes attempted by anonymous Senate staffers, officials or volunteers on the government network.

The targeted topics have included issues as diverse as Gamergate, "baby farming" and The Lord of the Rings.

The account was inspired by @parliamentedits, which tracks changes made from the UK Parliament IP, and is part of an entire community of bots that track everything from anonymous edits made from Russian government IPs to those made by anonymous staffers at the world's top media organizations.

The IP addresses, Wikipedia warns, are often shared by multiple users of a government agency or facility, though anonymous editing could be disabled if Wikipedia editors detect instances of vandalism.
