Revenge Porn is the sharing of private, sexual materials, either photos or videos, of another person, without their consent and with the purpose of causing embarrassment or distress.

The offence applies both online and offline, and to images which are shared electronically or in a more traditional way so it includes the uploading of images on the internet, sharing by text and e-mail, or showing someone a physical or electronic image.

‘Private materials’ are those showing anything not usually seen in public. Sexual material not only covers images that show the pubic region, but anything that a reasonable person would consider to be sexual so this could be a picture of someone who is engaged in sexual behaviour or posing in a sexually provocative way.
