The site is not scam, however in my opinion, the experts, the professional one, violate professional ethics. The site in turn violates confidentiality making the answers available to anyone who did not pay for it. Medical experts should not be allowed to answer online questions since no one can be diagnosed over internet and without taking responsibility for that. I submitted my suggestions to the site, but no changes were made. Someone has to question the legality of licensed professionals answering questions on this site.
