Wrong, lesns. If fact there is a whole body of work on how regulatory agencies respond to information from informants. Simple e-mails to the effect that "this is a scam," don't result in any action; they might get dozens of those a day.
High value tips, like StockLemon, Our-Street, etc. are extremely like to prompt action. First, they do much of the agencies work for them by documenting the fraud: second they set up political pressure for the agency to act on the information, because their inaction in the face of clear evidence can later be an embarrassment to them.
