The gil that was removed was players gil. It didn't get made by the rmt . Rmt farmed items players needed than players used there gil to buy said items. So the money removed was not "fake" or bad but was used for the wrong purposes (rmt).

There is only so many ways to make gil and when SE took out all that gil it was actually players gil that was made the right way. This scam is so messed up that everyone is involved unknowingly. If you ever buy from the market your helping rmt since they have so many items cornered.
