"Dr. Mercola explains that much of his success as a physician was due to his ability to treat arthritis, and a popular article describing his Arthritis protocol was consistently high on the list of search items for “arthritis.” Do that search today, however, and you won’t find that article. The top result, even when you search “Mercola arthritis,” is a Croatian website that copied, without permission, Dr. Mercola’s Arthritis article in its entirety. Dr. Mercola’s site ranks 9,002 in global internet engagement; the Croatian site ranks 9,401,920." https://anh-usa.org/dr-googles-prescription-censorship/
