Grooming means that an adult is getting to know and befriending a child with the intention of sexually abusing it. Grooming doesn’t have to be online, but the internet gives perpetrators the anonymity to act more freely and access to children who are not under direct parental supervision.
In the context of grooming, adults often pretend to be children, youngsters or "best friends" in order to gain the trust of their victims without showing their real identity. They aim to obtain intimate and personal data, involve the children and youngsters in sexual conversations and encourage them to send erotic pictures or videos. After reception of erotic material the perpetrator might blackmail the victim by threating him or her to send the picture or video to family members or friends in order to receive further material. Occasionally groomers even intent to set up a meeting to exploit the children "offline" as well.
