起因很简单：杰哥我想在WordPress Plugin: Target Adsense文章后面留言，因为我发现这个插件在firefox下面不能正常运行。但当点下提交留言的时候，出现了一个令我错愕不已的提示：【截图

Error 403

于是我跟着他的提示去看看，我所在的IP到底出了什么问题：【截图】

Technical Support

Your request was intercepted by security software which protects the Web site you visited from malicious activity, such as hackers, spam and viruses. We apologize for the inconvenience, but your request matched a profile of suspicious activity. This problem is usually quite easy to fix.

看上半部分的时候，我还以为我电脑中毒了，但看到下面关于我的IP上了黑名单的原因后，才感觉有些抓狂。再跟着链接提示看到了以下的内容：

再跟着链接来到dnsstuff.com，发现，我的这个IP上了更多的黑名单，杰哥我看着那些红色，刺眼无比。

原来220.175.0.0-220.175.255.255整个IP段全部被封锁了。我以前只知道QQ上屏蔽了512j.com，任何网址只要含有512j.com就发不出去。但没想到国外采取的是封IP的做法，而且是整个IP段。

做SPAM都做到国外去 ，而且还让人把整个IP段给封了，真他妈的厉害。

对于杰哥我这个江西的blogger以及其它的江西blogger来说，blog之间的留言和评论以及trackback在某些blogger上彻底失效了。
