Twitter prides itself as a place where everyone has “the power to create and share ideas and information instantly, without barriers”. In March 2018, it tweeted that it “stands with women to make their voices heard”. And yet, the right for women to freely express themselves is routinely silenced by toxic abuse on the platform. This abuse is compounded for women from minority racial, ethnic or religious backgrounds; not to mention women with disabilities; or lesbian, trans and bisexual women or people who don’t conform to gender norms of male and female. Ultimately, the scale and intensity of the abuse can and does drive women off Twitter – often costing them the networks they’ve painstakingly built on the platform.
