Child sexual abuse material consumers are easy targets because they fear police involvement.238 Members of commercial groups, by definition, are in the business of distributing child sexual abuse material for financial or other gain. While observers agree that the commercial child sexual abuse material-sector is large, estimates of its exact size vary. The United Nations Special Rapporteur on the sale of children, child prostitution and child pornography estimates that the criminal child sexual abuse material-market generates between US$ 3 billion and 20 ­billion annually.239 Other estimates place the market at US$ 250 million per year.240 Suppliers of child sexual abuse material may specialize in particular types of child sexual abuse material or operate multiple sites to cater to customers’ varying demands. Commercial groups may further operate child sexual abuse material websites as a means of obtaining credit card payment information for use in other crimes. A/HRC/12/23. Paragraph 44. UNODC, 2010.
