Oprah, Illinois AG Sue Internet Marketers

The complaint alleges that many consumers did not receive shipment of the trial supplements before they were billed and the companies made it nearly impossible to cancel future orders.

The suits are asking the court for a permanent injunction barring the companies from selling dietary supplements and continuing with misleading marketing schemes. The lawsuits also ask the court to pay restitution for consumers who have lost money and civil penalties of $50,000 for violating consumer fraud laws.

"We must hold these Internet scammers accountable for their role in a seedy marketing game that steers unsuspecting consumers to online schemes," Madigan said.

"We also need to send a clear message to other marketers and networks in the business of designing misleading, traffic enticing schemes."
