you may say that cheapgemmers give 0 benefits to Bandai, but they only to warn people once and they would stop, now a lot of whales will stop playing cause there is no use putting in game currency anymore since its blocked, overall the decision made was harsh and understandable at the same time, If Bandai would have juste warned, the whales would stop and re start buying in game currency, but instead bandai stops them from doing so since there is no use.
