Explanation
Online predators are individuals who contact other people usually women or children, to abuse them by virtual means such as social networks or chat rooms. Their actions are exclusive to the network, but in some cases, they attack their victims in real life. Usually, these predators contact the victims by showing themselves as friendly and reliable people and when they have already gained the victim's confidence they attack, these involve extortion, abuse or induce the victim to drug addiction or sexual behaviors.
