垃圾评论带来的流量流失

评论(4)

11月底收到一条短信提示,
说空间流量在月底前用光了,
之前每个月的流量最多用掉50%,
真实访问量没有增加的前提下怎么会20天用掉7.5G的流量,
因为11月底换了新空间,新空间的月流量为15G,
所以对于流量的流失也没有太在意,
谁换到新空间以后流量跑的更惊人了。
Transfer
12月3日竟然一天跑掉将近1G的流量,
长此以往有100g流量也不够用啊,
所以开始着手研究流量为什么跑掉。

流量为什么跑掉

还好,用的空间给提供最近3天的主机日志,
通过日志发现,流量是被来自福建莆田的一个不停更换ip地址的服务器每天数十万次垃圾请求给好用光的。
目测这个服务器是在一个拨号网络中,每隔一段时间会自动重新拨号以更换IP。
这台主机每天访问我的网站大概有30w次以上。
以下是截取了每天访问日志的冰山一角

59.58.159.32 [04/Dec/2013:14:55:18 GET /wordpress-ajax-comment-post
59.58.159.32 [04/Dec/2013:14:55:19] GET /wordpress-ajax-comment-post
59.58.159.32 [04/Dec/2013:14:55:19] GET /play-flv-in-html/
59.58.159.32 [04/Dec/2013:14:55:19] GET /play-flv-in-html
59.58.159.32 [04/Dec/2013:14:55:19] POST /wp-comments-post.php
59.58.159.32 [04/Dec/2013:14:55:19] GET /wordpress-ajax-comment-post/
59.58.159.32 [04/Dec/2013:14:55:19] GET /jquery-ctrl-enter-submit-form HTTP/1.1
59.58.159.32 [04/Dec/2013:14:55:19 POST /wp-comments-post.php

整个过程很简单,其实就是探测你当前的页面看看,然后再到你的评论提交页面提交垃圾评论。
这样很不容易被认定为是攻击访问。

从wp-comments-post.php入手

因为当前自制的主题是ajax提交评论的,所以对WordPress 自带的评论提交没有需求,
所以开始的时候我是直接将该页面删除了。
结果,所有请求都跳转到主题404页面,流量流失的更惨重了,所以失败!

从.htaccess入手

经过几番波折打算用.htaccess直接暴力屏蔽掉所有来自福建莆田的页面请求
这次流量下降明显,每天的流量降至300M多,每个月差不多也就10G左右的流量,
还是能够接受的。
具体的做法就是利用设置屏蔽来自福建莆田的几个IP段的请求,将请求都转至403页面
下面把.htaccess文件共享出来顺便感谢一下原作者

  1. 垃圾评论最讨厌了。

  2. @test
    社会化评论最大的坏处是不利于收录,
    我之前都是每天都至少上3次的,
    最近状态不佳,所以少上,批的晚些,见谅~

  3. 这个Ajax评论效果很好。不过建议还是用社会化评论吧,把这些审核工作交给专门做评论的人来要轻松很多

  4. 博主现在用的是哪儿的空间,在找虚拟主机。看到你在主机点评的链接点进来的。是西部的吗?
