"Anonymity increases the level of experienced fear, since potentially anyone could be the bully, including friends or other trusted people (Badiuk 2006; Mishna et al. 2009). Further, anonymity also increases the level of frustration, insecurity, fear, and powerlessness (Dooley et al. 2009; Nocentini et al. 2010; Slonje and Smith 2008; Smith et al. 2008; Vandebosch and Van Cleemput 2008). There is evidence that being bullied by someone you know and trust may be even more severe than by someone you do not know (Nocentini et al. 2010).
Anonymity changes up the entire playing field for bullies. The fact that it can be anyone behind the screen, or even lie about their identity and say that they are someone that the person is close to, could devastate the victim even more. Anonymity is also scary.
