That's a very nice comprehensive list of (F)alse "(E)vidence"(A)ppearing, (R)eal.
But it does not change the fact that liver flushes worked for me and my health improved tremendously following several of the liver flushes that I did. I have no need to "scam" anyone because there is no money to be made off of sharing my experience of success doing liver flushes. The olive oil industry is not pushing liver flushes, neither are lemon or grapefruit farmers, or evenEpsom Salt manufacturers. Therefore as anyone can see there is not a scam regarding liver flushes and there is no real incentive to produce a confidence game other than to bring the truth regarding personal experience that many people have had.
a confidence game or other fraudulent scheme, especially for making a quick profit; swindle.
As I already pointed out and you ignored there are people writing books pushing the flushes and even kits being sold. Thus it fits the definition of a scam.
