Thank you for this interesting question. Indeed the cyber violence against women is real as is stated in the European Parliament Report on hate speech online against women (2018) available in https://www.europarl.europa.eu/RegData/etudes/STUD/2018/604979/IPOL_STU(2018)604979_EN.pdf
The key findings are as follows:
• Increased data collection and large-scale research is necessary to grasp the scope of the phenomenon in the EU.
• A general directive on violence against women could be adopted and could address cyber violence and hate speech online against women.
• Member States have the responsibility to combat impunity online and should put emphasis on cooperation with other states when it comes to investigating and prosecuting perpetrators of cyber violence against women.
