Random girl comes on webcam to meet new people and is persuaded by random people (competing for points) to flash various body parts, not knowing that screen captures of video will surface on the world wide web within 30 seconds. The video will be traded on websites by hundreds of people and streamed. Videos are traded by collectors. Blackmailers get hold of the videos and information on the girls then hunt them and use the videos as leverage to get the girls under their control and command eg forced to do sex shows. Groups of heroes or 'white knights' who may also be paedophiles run around trying to save the girls from the blackmailing paedophiles. The Cappers and heroes fight to add the girls to their own collection. Source - the daily capper on u-tube for the week of August 15th 2010
The 2010 capper awards on you-tube granted awards to the cappers who captured the most screen shots of girls and to the most prolific sextortionist among those involved in capping.
