Maine regulators say some consumers in the state may have been victimized by an online Ponzi scheme. The Office of Securities and Bureau of Financial Institutions on Thursday said federal officials have taken action to stop the alleged “profit-sharing” scheme run through the website ZeekRewards.com. A North Carolina District Court placed ZekeRewards into receivership and ordered its assets frozen. The U.S. Securities and Exchange Commission charges that ZeekRewards and two other defendants raised $600 million from more than 1 million Internet customers and investors nationwide and overseas and operated a classic Ponzi scheme by paying the first wave of investors with new funds solicited from subsequent investors. Maine officials say some financial institutions in the state reported receiving requests for assistance from customers who invested in ZeekRewards.com.
