I agree that many crafters got too much gil due to the inflation caused by cheaters and gil buyers/seller and I even agree that taking money from them would be for the better of the game's economy. However, dividing their gil by 100 without any proof that they got it through cheating or illegitimate means is overboard. Even if they got more gil than they should have due to the inflation, they still got those gils honestly.

Of course, its entirely possible that all these whiners are in fact cheaters and gil buyers/sellers. Until SE gives a clear answer as to how they targeted people, we don't even know the real reasons why certain people were affected while others were not.
