The FTC just warned media outlets about advertising bogus products:

...the FTC staff has sent reminder letters to media outlets that ran advertisements challenged in the six law enforcement actions announced today. The purpose of these letters is to assist media in identifying and rejecting weight-loss ads that contain facially false claims. The media letters include: (1) a copy of the problem advertisement; (2) a copy of the Commission’s Reference Guide for Media on Bogus Weight Loss Claim Detection; and (3) a description of each Red Flag Claim contained in the problem advertisement.
