not only in fantia but also in dlsite and ci-en it seems that they have declared war to the westy banks due to the difficulties of refund games and monetary exchanges, plus there are other laws so now if you want to pay you have to go through an Asian bank or the Japanese paypal
As always, the Japanese ppl, instead of solving problems, decide to escape from them, so now they have lost the westy market because they are idiots. and this will further increase piracy due to the added difficulties of being able to pay and be legal.
