Yeah, some were able to expose him, but believers still believe. They say he had ringers in his audience. Regular people in the audience would discuss their situations and who they wished to connect with while waiting for the show to start and the ringers would overhear this and shoot the information back to his stage crew. He was always late to start (show starts at 1pm, but he would come out at 2:30) because he was taking notes backstage. There were also statements that much of his stuff was heavily edited (like when he appeared on tv talk shows) to cut out the many times he got it wrong.
