A credit card processing company in Latvia has been warned by the Michigan attorney general that it is violating the state’s laws against child pornography.

Rīga-based Trust-Bill.com is one of six companies Attorney General Jennifer M. Granholm said is breaking the law by processing credit card payments for Web sites that deal in child pornography. If the companies don’t stop accepting payments, they could face criminal prosecution.

“By going after the online money changers of the child porn world, we are trying to target a choke-point in the industry,” Granholm said in a press release. “Even if a Web site is located in a foreign country, we can cut off its business if we disable its ability to accept credit card payments from U.S. customers.”

The Trust-Bill.com domain name is registered to Anatoly Loginov, who is associated with a software company called SIA Sadeks, according to domain name and business data maintained by VeriSign and Lursoft Ltd. Latvians Online was unable to contact Loginov and Trust-Bill’s Web site could not be accessed as this story was being published.
