Peter Popoff
Popoff went bankrupt in 1987. But he made a comeback in the late 1990s. Beginning around the mid-2000s, he bought television time to promote "Miracle Spring Water" on late-night infomercials. He referred to himself as a prophet. The Business Insider said: "No matter how many times his claims are debunked, he seems to bounce back with another version of the same old scam."
