There is a new forum called Ask Humaworm which appears to be based on a product by the same name.
When Dr. Schulze visited the forum by his name he made some very negative remarks about products by Southern Botanicals and Dr. Christopher and claimed they were inferior to his. Even if his forum is more about support for his methods and to aid those who use them; Dr. Schulze himself seems to be as $$$$ oriented as Barefoot.
here is one link from the Schulze Forum : //www.curezone.org/forums/m.asp?f=321&i=7128#1
Although there may be varying degrees of blatant commercialism, I believe all forums based around either direct or implied pressure to buy products by the owner should be designated as commercial. Dr. Clark may be an exception. But even Andreas Moritz , as much as I respect him, openly hawked his books and other products.
I agree that Barefoot is the most blatantly commercial and high pressure, but he is not the only one.
