I think most people grossly overestimate the ability of government to act on fraud, scams and crime, even when there is information available. I see this with other scams & ponzi schemes. A common sentiment from both victims and con-artists is "if this is a scam, why haven't the police/government/etc... closed it down". All our governments are dysfunctional & ineffective to some degree and there just aren't enough resources to cope with everything and the burden of proof for action is high. Normally some political will is needed to prioritise an investigation into a particular company. Regulators are underfunded and outgunned by those whose massive profits rely on outsmarting them.
