The hackers' collective Anonymous have revealed the identities of about 1,000 alleged sympathisers of the white supremacist Ku Klux Klan (KKK) on the internet.

Anonymous said the data posted in Pastebin was "a form of resistance" against racial violence.

It is part of the mysterious group's year-long Operation KKK, which is a reaction or a "form of resistance" to the racial violence threatened and incited by the KKK last year, against those protesting over the killing of a young black man in Ferguson, Missouri.

In its release, Anonymous said, "We defend free thought and free speech. The anons responsible for this operation will not support *acts* of terrorism and *acts* of hate inflicted upon the public."

A list of alleged KKK members published earlier in the week appears to have been fake.

That list had incorrectly outed several US politicians as KKK members and was quickly followed by a denial from Anonymous's official Twitter account.

The new list includes names, aliases, Facebook and Google+ profiles, among other identifying details.

The Herald:

The names were said to have been gathered  over the course of the last year, using a variety of ways, from "interviewing expert sources" and "digital espionage" to obtaining publicly-available information.

 The list comes with a 1,000 word letter explaining the "anons" publishing the names "will not support acts of terrorism and acts of hate inflicted upon the public".

"We understand this initiative is extremely controversial and we know we will face much criticism for this operation and our work will be heavily scrutinized," the group said in its letter, before going on to say the data dump is intended as a "form of resistance against the violence and intimidation tactics leveraged against the public by various members of Ku Klux Klan groups throughout history."
