   The concept for Anonymous began when American-run imageboard 4chan, a website created in 2003 for sharing images with accompanying comments, followed in the footsteps of the Japanese imageboard 2channel by allowing an anti-signup system where comment posters could remain anonymous. 2018, Barney Warf, The SAGE Encyclopedia of the Internet, SAGE
