State insurance regulators are encountering sites designed to mimic ObamaCare's enrollment portal, the online hub where millions of people are meant to purchase healthcare coverage. Attempts at imitating healthcare.gov have met with cease-and-desist letters; the sites could confuse consumers seeking to enter ObamaCare's marketplaces. In New Hampshire, the insurance commissioner reportedly cracked down on one webpage last week that could have been mistaken for the state's insurance exchange. And regulators from Washington, Pennsylvania and Connecticut are warning the health insurance industry against creating sites that might mislead the public.
