Would there be less spam if Mechanical Turk cracked down on jobs like this?

Is this even against their policies? It strikes me as a hard policy to write. Compare it to "write and distribute a whitepaper about XYZ". That certainly sounds like a legitimate task, but it is only different from this example in scale.<p>At least if they decide to to forbid this practice, they can pay their own turksters to find and flag the forbidden activities.
