This article reviews a body of research on peer harassment mode called cyberbullying and its manifestations thorough Internet and social networks. Three thematic areas are introduced into which research has been directed: risk factors, emotional aspects involved in situations of risk, and intervention strategies to prevent complex situations that arise. It is emphasized the need to appreciate the complexity of moral, ethical, legal and educational aspects behind this type of interaction in society and the systemic relationships; those are rooted, reinforced and shaped by adult society. The starting point of this review is the need to recognize the limitations of some of the studies made and the importance of redirect research and those social and educational interventions. It is necessary to broad the spectrum of understanding and intervention to comprehensive perspectives in which personal, social and cultural factors become important.
