Due to AML regulations that you can read from this link, the deposit bank account and withdraw bank account from MondFx website, should belong to the owner of the account, with the same name and identity. So, depositing to the MondFx account and withdrawing from the MondFx account with other people’s bank account isn’t allowed due to the regulations.
To read the Anti-Money Laundering Rules, go to the KYC/AML page through the about us tab.
