The Silicon Valley, Calif., operators of RateMDs.com have removed two out of the seven most scathing comments about unnamed doctors cited by the Canadian Medical Protective Association (CMPA). But they ignored all other requests made of them by that organization and the Canadian Medical Association, the latter whose chief executive officer, William Tholl, also sent a recent letter saying he echoed the concerns of CMPA.

John Swapceinski, co-founder of the website, said the letters sent to him and co-founder Joanne Wong, were meant to be intimidating but, “I’ve developed a very thick skin since we first started this business.”
