"This document presents findings from a rapid review of available literature on what has worked to prevent cyber violence against women and girls. Key findings include: There is limited data on cyber violence against women and girls (VAWG) in general, and particularly on what works to prevent it [...] There are powerful international human rights frameworks which could be used to prevent cyber VAWG [...] However, the effectiveness of international human rights frameworks and laws is constrained by gaps in specialised national legislative and policy measures, mechanisms, procedures and expertise/skills [...] There are guidelines for social media companies but there are severe problems in getting them to enforce them/follow up [...] School-based interventions have potential to take primary prevention of cyber VAWG to scale [...] Various apps and online tools have been developed, but these are mostly not evaluated [...] Importance of contextualised, bottom up responses which acknowledge and address socio-cultural norms [...] Social media and the internet have also been used by women for online advocacy to combat VAWG."
