The girl told Liz she wanted to kill herself, but Liz continued demanding photos. She would speak to social services and get her disabled brother taken away and put in a home, unless the girl photographed herself in a series of degrading naked poses, holding up signs bearing messages such as 'I am a slut' and 'I look after my disabled brother, and now I am being forced to strip'. She threatened to mail photos to everyone in her street and school. 'I will do everything I can to make your life awful,' Liz told her. The trap quickly tightened: the more photos Victim 5 sent to Liz, the more she was blackmailed and the more explicit Liz's demands got. The girl was told that if she did not send more photos immediately, the one she had sent would be emailed to her bullies. She found a dog costing £275, and Liz told her she would buy it for her in exchange for a photo that 'absolutely nobody besides myself would ever see'. The girl confided to Liz that she lived in foster care, was being bullied by other girls and had a young disabled brother who 'meant the world' to her.

In return, Liz wanted the girl to email her a topless selfie as inspiration for a charcoal drawing. It was from Liz, an artist, who promised to pay for any dog she chose. One of the emails the 15-year-old schoolgirl received was strange. It started for 'Victim 5' in 2013, when she placed an advert on Gumtree saying she was looking to buy a pet dog. But in the modern world there are new ways to be cruel, and many of them are conducted from behind a computer screen. Torment and humiliation used to be a very public spectacle.
