BANDCAMPから返事が来た ちょっと今回はすごいので 後でTwitterにも書くけどこっちではメール全文書きます
「 To clarify what we mean by "returned to the rightful owner," the chargebacks we received indicated that these purchases were made by fraudsters using stolen or compromised credit cards. When we receive chargebacks for unauthorized purchase, the funds are returned to the card issuer, which means the refund will be issued to the rightful cardholder. Because this money was essentially stolen from the victims of credit card fraud, we're obligated to return those funds.」
最近 OMOIDEの作品が買われたあと返金されるという出来事が頻発していたんですが(つまり 例えばですが 1,500円で作品が買われた翌日に-1500という表示が出て儲けが消えていた)
それに対するBANDCAMP側の回答はこうでした
