这是一个不错的开端，但仍然并非密不透风。
我没说密不透风，我说的是足够可靠。实际损失会远低于信用卡造成的损失。

（例如，拒绝传播售货机处这笔交易的消息）
不，售货机会与一家大型服务提供商（也就是支付处理商）通信，后者向许多商户提供这项服务。可以把它想成是有了新工作的信用卡处理商。他们会拥有许多连接良好的网络节点。

This is a good start, but still not impermeable.
I didn't say impermeable, I said good-enough. The loss in practice would be far lower than with credit cards.
Quote
(for example, by refusing to propogate word of the transaction at the vending machine)
No, the vending machine talks to a big service provider (aka payment processor) that provides this service to many merchants. Think something like a credit card processor with a new job. They would have many well connected network nodes.
