The vow to post KKK members’ names online marks an escalation in a year-old battle between the two groups, which began during civil unrest in Ferguson, Missouri.

Official #OpKKK #HoodsOff 2015 Press Releasehttps://t.co/NUtywLI3jz — Operation KKK (@Operation_KKK) October 27, 2015 In a press release, Anonymous says it is right for the group to unveil the hoods behind the Ku Klux Klan. Anonymous said it has been watching the group for so long and revealing the people behind the hoods is “the right course of action.” Anonymous has also asked a vote on Twitter from its followers and members whether it should remove the hoods off the KKK member or not.

— Operation KKK (@Operation_KKK) October 28, 2015 In November 2014, during the wait for a grand jury’s decision whether to indict police officer Darren Wilson for the killing of Michael Brown, the KKK reportedly threatened to attack Ferguson protesters. Anonymous then commandeered a KKK-linked Twitter account and exposed social media accounts it said belonged to KKK members. Now after a year, when the grand jury elected not to indict Wilson, Anonymous published a blog post on Wednesday that it “will release, to the global public, the identities of up to 1,000 klan members, Ghoul Squad affiliates and other close associates of various factions of the Ku Klux Klan across the Unites States.”
