Bad Behavior , a competing rather effective comment spam prevention plugin, author nicknamed IOError posted a 不良行为 ，竞争，而不是有效的防止垃圾评论的插件，作者绰号IO错误发布了 review复习 which points out some obvious downsides of such centralized spam filtering mechanisms like:其中指出，一些明显的缺点这种集中的垃圾邮件过滤机制，例如：
1. 1 。 Privacy concern - all your comments are send to Matt’s server for human inspection隐私的关注-所有您的意见发送给马特的服务器供人查阅
2. 2 。 So far the spam comments are actually marked by humans and hence not scalable - Please see comments by MacManx below for an update. 直至目前为止，垃圾邮件的评论，其实是标志着人类，因此没有可扩展 -请参阅评论m acmanx下面的更新。

Since I have added this program, I have been witness to a great decrease in the spams I have received.既然我已经加入这一计划，我已见证了一个伟大减少，在垃圾邮件，我收到了。 Matt’s plugin, called Automattic Spam Stopper (now renamed AKismet) has been tweaked a few times and the spams have been reduced and reduced until it has become an anomaly that any one will get through.马特的插件，所谓的automattic垃圾邮件的塞子（现改名为akismet ）已扭曲几个时代和垃圾邮件已显着降低，并减少，直到它已成为一种反常现象，任何人会得到通过。

Aside -除了-
Is comment spam such a huge problem?是垃圾评论如此庞大的问题呢？ I think recently it is getting more hype than it is worth.我认为最近是越来越炒作比是值得的。 I have been using我一直使用 few simple measures to stop WordPress comment spam几个简单的措施，以制止在WordPress垃圾评论 for 9 months.为九个月。 On average I spend 5-10 minute a week deleting comment spam attempts or approve new comment authors, sometimes less.就平均我花5-10分钟一个星期删去垃圾评论的企图或批准新的评论作者，有时少。

Back to AKismet / Automatic Spam Stopper -回到akismet /自动垃圾邮件塞子-

I think a de-centralized approach to handling comment spam within a simple framework / plugin has more chance of success that a centralized approach for several reasons.我认为，一个由集中的方式来处理垃圾评论在一个简单的框架/插件有更多成功的机会，一个集中的做法，原因有几个。

A single barrier like Matt’s (you get the idea) is much easier to breach and when the payback is so high spammers can spend lots of resources to defeat it.一个单一的屏障一样，马特的（你的想法）要容易得多违反时，投资回报是如此高的垃圾邮件发送者可以花大量的资源来战胜它。 It just makes economic sense for spammers to go after Matt’s err.它只是使经济意识，垃圾邮件发送者去后，马特的错误。 solution.的解决办法。

Also a spammer can pose as a legitimate blogger, glean information about comments Matt marks as spam and gain useful information to subvert the system.也是一个垃圾邮件发送者可以构成一个合法的Blogger ，收集信息的评论马特马克为垃圾邮件，并取得有用的资料，颠覆制度。

Such a schema can be subverted by man-in-the-middle-attack, impersonating Matt’s server.这样的架构可以颠覆男子-在- -中攻击，冒充马特的服务器上。

It is very vulnerable to DDOS spam attack against Matt’s spam managed blogs.这是很容易的DDoS攻击，垃圾邮件对马特的垃圾邮件管理的博客。

A strong de-centralized barrier like一个强大德集中屏障一样 Bad Behavior不良行为 or CAPTCHA based ones or或基于个案的Captcha或 my combination solution我相结合的解决方案 provides a stronger protection en-masse against spam.提供了一个有力的保护-集体反对垃圾邮件。 The variety of solution actually makes it much harder to go after and doesn’t make much economic sense.各种各样的解决方案，实际上使得它更难去后，并没有多大的经济意义。

Also they are not vulnerable to DDOS attack like Matt’s solution.此外，他们是不会受到DDoS攻击一样，马特的解决方案。

What can be done is selectively share certain information by spam referrer’s or compromised machine lists etc. to improve the solutions.可以做些什么，是有选择性地分享某些资料，垃圾邮件引荐的或妥协的机器名单等，以改善解决方案。 However not a fully-outsourced solution like Matt’s.不过，并不是一个完全外包的解决方案一样，马特的。
