The registry has been built by parents and schools and each month spammers have to pay to have a designated third party examine their marketing lists for addresses that appear on the registries. The cost for a business can total thousands of dollars, and violators face stiff fines. Last month, the FTC said such registries pose serious "security and privacy risks."
It is worried that the list could fall into the hands of paedophiles. They also are a bit worried that a paedophile ring could pose as spammers and bounce email addresses off the register until they can get children's emails .
Other groups say the measure will not work because most porn spam comes from overseas so it is a tax on law abiding US spammers in favour of those foreign devils.
