其他参与者原话Insti原帖 ↗它弊大于利，因为它阻碍了 bytemaster 提议的那类小额支付实现。
It seems to do more harm than good because it prevents micropayment implementations such as the one bytemaster is suggesting.
Bitcoin 目前还不适用于非常小额的微支付。像按次搜索或按页浏览这种没有聚合机制的做不到，需要支付低于 0.01 的也做不到。灰尘垃圾限额就是对故意阻止这类过小额微支付做的第一次尝试。
Bitcoin isn't currently practical for very small micropayments. Not for things like pay per search or per page view without an aggregating mechanism, not things needing to pay less than 0.01. The dust spam limit is a first try at intentionally trying to prevent overly small micropayments like that.
对于比现有支付方式更小的交易，Bitcoin 是实用的。小到足以涵盖你可以称之为微支付区间顶端的那部分。但它并不声称适用于任意小的微支付。
Bitcoin is practical for smaller transactions than are practical with existing payment methods. Small enough to include what you might call the top of the micropayment range. But it doesn't claim to be practical for arbitrarily small micropayments.
