There is a battle going on between Science and Quackery

Hulda Clark, the number one quack in Canadian Quack Watch,

believes that many major medical conditions are caused by parasites, or flukes. She says that she can diagnose them and then cure them by using cheap electrical devices that she calls "zappers" or "syncrometers". Then add in a few herbs, remove your amalgams, and there you have it, A cure for all diseases. Her naturopathic degree is mailorder, her Tijuana clinic was closed down by Mexican authorities for cancer and alternative medical treatment. When she was arrested in 1999 for practicing medicine without a license in Indiana, she hired Tim Bolen.

Bolen has followed the activities of the "quackbuster" for about five years:

The "quackbuster" operation is a conspiracy. It is a propaganda enterprise, one part crackpot, two parts evil. It's sole purpose is to discredit, and suppress, in an "anything goes" attack mode, what is wrongfully named "Alternative Medicine." It has declared war on reality. The conspirators are acting in the interests of, and are being paid, directly and indirectly, by the "conventional" medical-industrial complex.

He speaks of the last days of the quackbusters, evilness, the quackbusters stronghold, and claims about what "health fraud" really is.

He runs the North American Consumers Against health fraud.

And he (Bolen) fights science with quackery:

Schrolling down here you might find other info sources, amongst others containing a list of "health freedom advocates".

On further consideration those webpages should be tested like this: do they claim to cure a wide range of unrelated diseases? do they have personal case histories that have been passed on from person to person? do they promise to treat diseases quickly?do they suggest that product are safer than conventionel treatment? do they claim it's a miracle cure? do they garantee satisfaction or money paid back? do they use paranoid accusations?

Answering yes to more than one of theese question indicates it could be recognized as health fraud.
