Hurtcore

Hurtcore, a portmanteau of "hardcore" and "hurt", is a name given to particularly extreme pornography, usually involving degrading violence and child sexual abuse. Eileen Ormsby, Australian writer and author of "The Darkest Web", described hurtcore as "a fetish for people who get aroused by the infliction of pain, or even torture, on another person who is not a willing participant". An additional motivation for the perpetrator next to his position of power over his victim can be the reaction of his victim to the physical abuse like crying or screaming out of pain. This reaction can stimulate the arousal of the perpetrator even more.
A subculture of the pedophile community, hurtcore is outside the limits of acceptable behavior for most pedophiles, and generally banned from pedophile websites. Some dark web forums are dedicated to the discussion, and the sharing of images and videos, of hurtcore.
In 2013, "Hurt2theCore" was the dark web's most notorious hurtcore forum, run by Matthew Graham, who became known as the "King of Hurtcore" and "one of the biggest child pornography and hurtcore distributors in the world".
The case of Matthew Falder is the National Crime Agency's first successful hurtcore prosecution.
Infamous hurtcore video "Daisy's Destruction", created by Peter Scully, was streamed on hurtcore websites.
