A PREDATORY paedophile pressured a teenage girl into cutting herself while he watched on a webcam.
Lee Christie, 43, of Barnby Gate, Newark, told the girl he would send indecent pictures of her to her parents unless she obeyed.
He was jailed for eight years on Tuesday for terrorising a number of girls online.
He pretended to be a teenage boy to persuade victims to strip and carry out indecent acts, manipulating and threatening ten victims aged 13-16, and accumulating thousands of indecent images of children.
Christie admitted 23 charges and was sentenced at Nottingham Crown Court.
His home was raided by police in January last year, and 70,000 indecent images and videos of children were found on two computers, as well as another 3,000 images of extreme pornography.
He was arrested after a tip-off from the Child Exploitation Online Protection Centre who intercepted him on a US social networking site. Detective Constable Andy Taylor said: "He would first get them to trust him before persuading them to take their clothes off online. Once he had images of them, he would blackmail them to do what he asked."
He also took indecent images of two girls, then aged 13 and 14, in Notts in 2004.
He admitted 15 counts of making indecent images of children, possession of 69,542 indecent images of children and six counts of causing a female aged 13 or over to engage in sexual activity.
He also admitted possession of extreme pornography and a prohibited image of a child.
He will sign the sex offenders register for life.
