如何防止 Trackback Spam
现在无忧博客有不少用户可能都遭遇了 Spam 评论。
Tackback Spam 是如何产生的？
您可能会奇怪，评论留言不是需要验证码的吗？怎么还有这么多的垃圾留言？
其实，这些垃圾留言，不是采用普通的“登陆您的站点->查看文章->提交留言”这样的形式来提交的，而是采用 Trackback 方式产生（有关 Trackback 的介绍，参见《什么是 Trackback？如何使用？ 》）。这样的引用通告形式留言，验证码不能起作用。因此，有人利用这类的漏洞，使用相关工具在互联网上大量发布这类垃圾留言。
如何避免垃圾留言？
这类 Trackback Spam 和垃圾邮件一样，十分令人生厌。为此，无忧博客最近对 Trackback 功能进行了一些修正，更改了默认的 Wordpress Trackback 链接形式，希望能够起到一些防止作用。但这样的修正，并不能保证完全避免此类垃圾。如果在您的博客中，这类垃圾评论很多，您希望从根本上杜绝，可能还需要您做一些工作，或者牺牲一些功能。 杜绝 Trackback Spam 最简单的方法是：不允许 Pings。您在发表文章时，在右侧“讨论”选项中，取消选择“允许 Pings”。要更加彻底，您可以在管理后台“选项”菜单下的“讨论”选项中，取消选择“允许接受来自其它网站的通知（Pingback 和 Trackback）”，这样，您就不用每次在发布文章时处理是否允许 Pings 了，默认就是不允许。
这样不允许 Pings 的处理，难免会牺牲这个功能，但在垃圾评论很多的博客中，这也是不得已的办法。如果您的博客中此类垃圾评论并不是很多，只是偶尔出现，您也可以设置一些评论的选项：如“评论必须通过管理员审查（除非它符合您所设定的过滤列表）”。
更好的办法是使用插件“Simple Trackback Validation”，它可以通过一些技术检查，来判断Trackback 是否是 Spam。

How to put “Simple Trackback Validation” into my directory, please?
请问：为什么我的评论不能发表？谢谢！
你说的早已过时, 很多博里都在受到骚扰. 看看你这个博文的颜色, 就知道你们并不替他人着想. 这还是让人读的么?
就知道为了几个破点击率, 兴师动众, 大张旗鼓的.
