GAE上的博客经常受到垃圾评论的骚扰，可以将留言的IP添加到GAE的DoS里面，具体步骤很简单，新建一个dos.yaml文件，代码如下：

blacklist:
- subnet: 1.2.3.4
  description: a single IP address
- subnet: 1.2.3.4/24
  description: an IPv4 subnet
- subnet: abcd::123:4567
  description: an IPv6 address
- subnet: abcd::123:4567/48
  description: an IPv6 subnet

GAE官方的解释如下：

A dos.yaml file in the root directory of your application (alongside app.yaml) configures DoS Protection Service blacklists for your application. The following is an example dos.yaml file:

The syntax of dos.yaml is the YAML format. For more information about this syntax, see the YAML website.

A dos.yaml file consists of a number of blacklist entries. A blacklist entry has a subnet, and can optionally specify a description. The description will be visible in the Admin Console. The subnet is any valid IPv4 or IPv6 subnet in CIDR notation.
