There is a difference, I guess, in posting links to sites and blogs that sell the meds directly and posting links to blogs that only have adsense or Amazon links. ICU doesn't tell you to buy at any certain place in her protocols, she just gives you links to where you can buy them.
You, on the other hand, post research on a site where you openly sell the meds. I guess they see it as you saying "Here's the research about what to take, and you can buy it right here." It would be like Bayer posting research on how aspiring treats headaches better than anything...and oh, btw, WE SELL ASPIRIN! How convenient is that?
You know, Dr. Mercola did not sell a thing on his site for years. He only posted information. People started to trust him, THEN he started introducing products. Smart man.
