The Spamhaus Exploits Block List (XBL) is a realtime database of IP addresses of hijacked PCs infected by illegal 3rd party exploits, including open proxies (HTTP, socks, AnalogX, wingate, etc), worms/viruses with built-in spam engines, and other types of trojan-horse exploits.该SpamHaus说，利用封锁清单（ xbl ）是一个实时数据库的IP地址被劫持的电脑感染了非法第三党利用，包括开放式代理（ HTTP的，袜子analogx ， Wingate ，客户等） ，蠕虫/病毒具有内置的垃圾邮件引擎，和其他类型的木马-马功勋。 I was recently testing this list againt spam email.我最近测试这份名单againt的垃圾邮件。 Here are few observations from our testing.这里有几点意见，从我们的测试。

XBL is effective in catching comment spams. xbl是有效的在追赶评论垃圾邮件。 However I have also seen several false positives where genuine comments were flagged as spam by xbl database.不过，我也看到几个假阳性的地方真正的评论被标帜为垃圾邮件xbl数据库。 This is not surprising by itself.这是不足为奇的本身。 XBL includes list of IP addresses which are hijacked. xbl ，包括IP地址列表，这是被劫持。 However most of the time the owners do not know that their PC’s have been hijacked.不过大部分的时间，业主不知道他们的PC的已被劫持。 As it happens such owners also want to participate and make comments.因为它发生这样的业主也想参加，并作出评论。 Working from a compromised PC doesn’t automatically make them spammers.工作从一个妥协的PC不会自动使它们垃圾邮件发送者。 However there is more to it that just that.不过有更多的给它，只是。

The XBL wholly incorporates data from two highly-trusted DNSBL sources, with tweaks by Spamhaus to maximise the data efficiency and lower False Positives.该xbl完全整合的数据从两个高度信任dnsbl消息人士透露，与调整，由SpamHaus说，尽量提高数据的效率和较低的假阳性。 The main components are:主要组成部分是：
- the CBL (Composite Block List) from cbl.abuseat.org -跨湾连接路（复合砌块的名单）由c bl.abuseat.org
- the NJABL Open Proxy IPs list from www.njabl.org. -n jabl开放代理服务器的I P清单，从w ww.njabl.org。

It appears XBL team is already working to eliminate false positives.看来， xbl队已经工作，以消除假阳性。 The problem is that in many countries like India, IP addresses are mostly allocated dynamically.问题是，在许多国家，如印度， IP地址都是动态分配。 Many people also connect over dial-ups.很多人也连接拨号的UPS 。 Such users have a high likelihood of being identified as spammers with XBL.这些用户具有很高的可能性被认定为垃圾邮件发送者与xbl 。 They are not necessarily using a compromised PC.他们不一定用妥协的PC机。

Note: XBL was not designed to catch comment spams.注： xbl的目的，并非要赶上评论垃圾邮件。 It was primarily designed for catching email spams.它主要是用来捕捉滥发电邮。 However the usage is valid because both kind of spams share many common characteristics and can leverage common technologies such as blacklists.不过，使用是有效的，因为这两个种垃圾邮件有着许多共同的特点和可以利用的共性技术，如黑名单。 Both can be done manually and also heavily automated.双方可以做的手动和也构成沉重的自动化。 Both are used to advertise same type of products.两者都是用来做广告同一类型的产品。
However there are differences too which needs to be kept in mind while designing anti-spam solutions.不过也有差别太需要，必须铭记，而设计的反垃圾邮件解决方案。 Comment spam is by far much easier to intercept than email spam in my experience.垃圾评论是迄今为止容易得多拦截比滥发电邮在我的经验。

In Comment Guard plugin I have decided to remove XBL because of the false positives.在评论民警卫队插件我已决定，以消除xbl ，因为该假阳性。 Comment Guard Pro is designed to eliminate false positives from comment spam detection (as well as false negetives).评论民警卫队Pro是旨在消除假阳性，从评论的垃圾邮件检测（以及虚假negetives ） 。 Any任何 source来源 of false positives, however valuable, is simply not acceptable.的假阳性，但宝贵的，只不过是不能接受的。
