"#GamerGate" is an online movement ostensibly concerned with ethics in game journalism and with protecting the "gamer" identity.
GamerGate refers to the online backlash against perceived breaches of journalistic integrity on video game news sites that occurred as a result of the Quinnspiracy, an online controversy surrounding indie game developer Zoe Quinn's alleged affairs with a number of men working in the video game industry, including Kotaku staff writer Nathan Grayson. The term has also since been used to describe the group of internet users, based mainly on Twitter, who claim that there is a lack of transparency within the video game journalism industry. These same people have also been criticized of practicing misogyny and sexism by many, through harassment and trolling, referring to their opposition as social justice warriors.
The Gamergate controversy stemmed from a harassment campaign conducted primarily through the use of the hashtag #GamerGate. The controversy centered on issues of sexism and progressivism in video game culture. Gamergate is used as a blanket term for the controversy as well as for the harassment campaign and actions of those participating in it.
In August 2014, the harassment campaign targeted several women in the video game industry; notably game developers Zoë Quinn and Brianna Wu, as well as feminist media critic Anita Sarkeesian. After Eron Gjoni, Quinn's former boyfriend, wrote a disparaging blog post about her, #gamergate hashtag users falsely accused Quinn of an unethical relationship with journalist Nathan Grayson. Harassment campaigns against Quinn and others included doxing, threats of rape, and death threats.
