Wizardchan
After Zoe Quinn accused the Wizardchan user base of harassing her, NeoGAF banned users who defended Wizardchan.

Gamergate

 * On or around September 11, NeoGAF banned the account of The Fine Young Capitalists.
 * On October 8, 2014, Treemasterx was banned from the NeoGAF forums for asking opponents of the Gamergate investigation to justify their position. The ban message was "You are a poor fit for NeoGAF." Treemasterx's final post before being banned was:

What I mean is that there are people who want to make "Cool" Female Characters, but people like Anita Sarkisian want a character to fit into all their check boxes. Woman, Check. No boobs, check. Black, check. Strong, check.

Instead of filling all these checkboxes, just make an interesting or "Cool" Female Character. Someone who has a personality and someone who we care about.

On October 12, Boogie2988 was banned for discussing Gamergate.
