The hacktivist group Anonymous says it will release the names of more than 1,000 Ku Klux clan members on Thursday as part of its continuing online attack against the white supremacist group. Earlier this week, Anonymous announced it had infiltrated the KKK’s Twitter accounts and websites, and names of some purported KKK members began to surface.  But a person or group known as Operation KKK, which says it is affiliated with Anonymous, tweeted that it had not released the information and invited readers to return back at 11 a.m. ET Thursday for their list.
