I am sorry but your mt-tb.cgi was loading up your server to over 100:

top - 15:00:03 up 8 days, 12:42, 3 users, load average: 106.36, 74.61,
54.69

Simply by disabling it I was able to get the load back down quite a bit
(and it is still dropping):

top - 15:06:54 up 8 days, 12:49, 2 users, load average: 3.86, 43.62,
51.09

I am sorry I had to rename it but we can't let one user jam up an entire
server like that unfortunately.

竟然由于TrackBack Spam的攻击，导致虚拟主机的负载过高，被DH关闭了mt-tb.cgi的使用。

为解决此问题，我采用了以下几种方法，暂时抵御这可耻的TrackBack攻击。

1. 安装CCode and TCode。
2. 修改mt-tb.cgi为其它文件名，并在mt-config.cgi文件中指定TrackbackScript为新文件名，然后重建Blog。
3. 可能的情况下，将Movable Type转用FastCGI替代以 cgiwrap 或 suexec 方式运行的CGI，然后重建Blog。
4. 关闭收到过多垃圾引用通告的日记，切断这些已经被Spamer列入重点攻击对象的日记继续被攻击的可能。

当然，这些方法不可能从根本上消灭Spam攻击，TrackBack这种实用的功能要想得到更进一步的推广，更好的发挥自己的效用，还要在底层设计上就考虑好Anti-Spam。
