Echoing the wise words of others. Keeping the prices at their natural high will lower the prices quicker and more naturally than if they are supplemented or fixed (current US economy anyone? bailout?). The other option would be for Turbine to actually punish the exploiters which hasn't happened yet (and no, a temporary ban is not a punishment equivalent to the offense of unlimited gold and +3 tome exploiting). Since Turbine is not doing the later, the best option is to just wait it out until the dirty money gets used up and things go back to normal.
