The mysterious online activist group, Anonymous, stated publicly on Monday that it intends to release the names of over one thousand members of the Ku Klux Klan. It has been just about one year since Anonymous began investigating the Klan in the aftermath of the protests in Ferguson, Missouri.

On Monday, Anonymous released its first names which included 23 email addresses as well as 57 telephone numbers, according to The Huffington Post. The activist group clearly identified those listed as members of the Ku Klux Klan. Many, including the mayor of Lexington, Kentucky, immediately took to Twitter and the media outlets to disavow the information posted at PasteBin stating that they are, indeed, members of the Ku Klux Klan. Some of the listing included the spouses of those accused of Ku Klux Klan membership.

Anonymous announced that it will release the remainder of its gather names, over one thousand of them, on Thursday, November 5. Someone named “Amped Attacks” on Twitter stated that he was not affiliated with Anonymous and that he was acting on his own without their help. Amped Attacks seems to already gained notoriety for having attacked purported websites belonging to, or affiliated with, the Ku Klux Klan.

The names are said to include many U.S. mayors as well as a few United States Senators. Ample Attacks said publicly that he has verified all of the names. He said he was able to do that by hacking into several Klan websites and emptying their databases of membership names. Anonymous did try to gain some separation from Ample Attacks in a tweet. The group tweeted that it would not publish anything until they could independently verify the information.

Everyone listed on the initial dump has denied everything, of course. They state that they are in no way affiliated with the Ku Klux Klan and have never been. Anonymous had originally begun to mount an offensive against the Klan when the Klan stated publicly that “lethal force” needed to be used against those who were protesting in Ferguson.
