but, the BBB is a private ratings agency. why has the market not corrected itself?
It has. The BBB provides worthless ratings and the market values them at approximately $0.
you seem to have an unusual definition of "the market".
are you limiting the market to "bitcoin users" or "technorati" rather than the general population of people who buy things?
Its in its way of happening then. If BBB was a government agency there would be no way to "fight back". You would have to finance it through taxes and shut up.
