当有更高竞价时，它将试图退款给曾经最高竞价人，如果退款失败则会抛出异常。这意味着，恶意投标人可以成为当前最高竞价人，同时确保对其地址的任何退款**始终**失败。这样就可以阻止任何人调用“bid()”函数，使自己永远保持领先。建议向之前所说的那样建立[基于pull的支付系统](https://github.com/ConsenSys/smart-contract-best-practices/#favor-pull-over-push-payments) 。

另一个例子是合约可能通过数组迭代来向用户支付（例如，众筹合约中的支持者）时。 通常要确保每次付款都成功。 如果没有，应该抛出异常。 问题是，如果其中一个支付失败，您将恢复整个支付系统，这意味着该循环将永远不会完成。 因为一个地址没有转账成功导致其他人都没得到报酬。
