Details of 1,000 KKK sympathisers released by Anonymous
Anonymous, a loose coalition of hackers, said the data was "a form of resistance" against racial violence
Anonymous has shared details of about 1,000 alleged Ku Klux Klan (KKK) sympathisers on the internet.
It follows threats from the white supremacist KKK to use "deadly force" against those protesting about the killing of a black teenager in Missouri.
Anonymous, a loose coalition of hackers, said the data was "a form of resistance" against racial violence. A list of alleged KKK members published earlier in the week appears to have been bogus.
The list appears to detail social media profiles of people who had joined or "liked" KKK-related groups on Facebook and Google+. Many of the profiles featured racist imagery and slogans.
Anonymous said it had used human intelligence - not hacking - to create the list.
"This means that individuals on this list were often identified by human sources of information through both overt (interviewing expert sources) and covert (digital espionage/social engineering) methods," a statement accompanying the list read.
A separate list posted online earlier this week incorrectly outed several US politicians as KKK members and was quickly followed by a official Anonymous denial from its @Operation_KKK Twitter account: "The anons at the helm of this initiative vouch ONLY for the dox list that will be released from this Twitter account on November 5 2015", it said.
5 November is a significant date for members of Anonymous because it is the day that Guy Fawkes attempted to blow up the English Parliament in 1605. Guy Fawkes masks, made popular in the movie V for Vendetta, have become a symbol for the group.
The group launched its latest campaign, dubbed Hoods Off, after the Ku Klux Klan threatened violence against protesters in Ferguson, Missouri. People, including Anonymous members, took to the streets after a jury decided not to prosecute a white police officer who had shot a black teenager in August 2014.
