An anti-bullying charity called Ditch the Label, which studies the prevalence of cyberbullying on social networking sites, has recently conducted a large-scale survey for those who had been bullied: 46% of the respondents stated that they have been bullied more than once, and 20% have bullied others on social networking sites (Chan et al., 2021, p. 1). In addition, there are findings that school bullying is not only related to psychological behaviors related to suicide, but also psychological behaviors related to murder (Guo-Bao et al., 2019, p. 7). Bullying on social networks can cause suicide. Because the person who is bullied is exposed to serious psychosocial harm (such as depression) and physical harm (such as self-harming behavior), as a result, he tends to commit suicide. For example, a young girl who was bullied on social networks shot herself, and the incident resulted in death (Chan et al., 2021, p. 1).
