Cyberbullying can be seen as a form or extension of bullying, perpetrated via digital media, and is also an aggressive, intentional, and persistent behaviour. It can happen anywhere, at any time, and all the time.
While in bullying the aggressor is known, in cyberbullying the aggressor is often anonymous, there is a physical distance, the aggression comes through mobile phones, social networks and messages, which contributes to the complexity of the phenomenon and to the aggravation of the emotional consequences for the victims.
Sometimes victims of bullying can become perpetrators of cyberbullying. Previous bullying, social withdrawal and isolation, lack of parental supervision can lead to cyberbullying.
