…[M]ore child porn consumers are moving to the use of pre-paid credit cards to mask their identities. Unlike traditional cards which require names, addresses, and bank information, pre-paid cards can be purchased with cash at gas stations and drug stores…allowing child porn buyers to remain almost completely anonymous. One way to prevent this sort of abuse is to require people to provide proof of identity when purchasing pre-paid cards…But credit companies have been less than enthusiastic about adding new requirements…Several of the major credit card companies have been engaged in combating child pornography by working with law enforcement and notifying banks when a child pornography site is identified. But despite the good work companies have engaged in, the financial incentive is still for them to overlook or take minimum action against child pornography, which generates billions of dollars.
