Wow. I checked out one of their threads about anti-Gamergate and read a little. I've seldom seen such an echo-chamber and circle-jerk. How can a site be infiltrated and completely transformed like that? Of course, like you say, by banning and cleansing you can purify a community similar to what happened in the Soviet Union and China during the Cultural Revolution, but I wonder how the social justice movement did to infiltrate and overtake the NeoGAF leadership.
I'm about to throw up now.
Oh, you should see all the Anita Sarkeesian and Zoe Quinn threads. They're even worse. I have never seen so many obsessive sycophants in one place until I took peek.
