Regardless of what he may have done in the past, his show still provides a great forum to discuss Bitcoin news and for business types to announce their new ideas and products. So I still support him and am glad he's continuing to do the show. Frankly, I think he has done way more for bitcoin and its surrounding businesses than most people here, scammer or not.
His show provides a great forum for him to continue to scam people. What ever good he may have done (and I don't think his pump and dump ways did Bitcoin any good, although some speculators may have made some money ) has gone right out the window. For him to continue to act like some spokesman will continue to harm Bitoin's rep when people find out about his scams and associate that with Bitcoin itself.
