The benefits of a free market are derived from its transparency. Resources are driven to where they fetch the best price. The idea is that scores of market participants will better allocate their funds to needed resources than any centralized planning bureau. When market participants act to reduce transparency by colluding behind the scenes, spreading false information, etc. they impede the free market from working.

So to answer your question, any behavior that reduces market transparency should be prohibited.
