Thanks to Joe for sending along some links about the ongoing downfall of BioPerformance, Inc. (discussed in the hoax forum in this thread about fuel additives). To summarize briefly: BioPerformance seems to be a classic case of a pyramid scheme. The people at the top of the pyramid were convincing suckers to pay for the privilege of selling little green pills that supposedly, when placed in a car's gas tank, yielded "vast improvements in mileage, performance and emissions". What BioPerformance wasn't telling anyone was that the pills were simply mothballs that didn't improve mileage and could actually ruin a car's engine. (Though oddly enough, according to the Dallas Observer article, mothballs can, under certain conditions, boost octane levels, which can help engine performance... but only when used in very carefully controlled amounts and in high-performance engines.) Sadly, in a classic example of cognitive dissonance, many of the BioPerformance faithful are refusing to admit they've been scammed. But thats always the way it is with con-artists and their victims.
