Women's and queer voices are being silenced by harassment and targeted attacks on the internet. Online gender-based violence (GBV) takes many forms including harassment, hacking, impersonation, surveillance/tracking, spamming, the non consensual distribution of intimate photos and messages and recruiting victims into violent/harmful on ground situations. The prevalence of online GBV is an exacerbating factor in women's digital exclusion. Yet unfortunately, we have limited data on the extent of online GBV and particularly on what works to prevent it. From IDRC-funded research in Latin America, Asia and sub Saharan Africa, we have a growing body of knowledge on the profound gaps in access, use, and basic skills, disaggregated by gender binaries. But for security and safety, rights, participation and expression – there is a dearth of statistically significant research on how women and LGBTQI communities experience the online world and the levels of harassment and violence they face. Female public and political figures from across the world, for instance, report disturbing levels of abuse on social media platforms like Twitter. But in the global South, we only have the personal accounts of attacks on women, gender-diverse, transgender and queer populations as they navigate the digital ecosystem. Global South countries are only rarely included in public opinion polling on Internet issues, in part because of the lower Internet penetration rates and in part because logistical and capacity challenges increase costs. Thus, other than these anecdotal accounts, nearly all available research comes from the Global North, like the Pew study from the United States in 2017 which showed that 41 percent of Americans reported experiences of harassment online, and 70 percent of women said online harassment is a major problem. Furthermore, the fast pace of technological change and contextual differences in platforms used in different countries makes it challenging to design and evaluate responses that are appropriate to multiple regions and platforms.  This initiative seeks to conduct a global statistically significant survey of people's experiences online, with a focus on online gender-based violence and deep dives into women's/LGBTQI+ online experiences in a set of countries in the Global South. Armed with this data, development, private sector and government actors can better design responses to online gender-based violence – through regulation of online social media platforms, education programs or legal recourse.
