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.該SpamHaus說，利用封鎖清單（ xbl ）是一個實時數據庫的IP地址被劫持的電腦感染了非法第三黨利用，包括開放式代理（ HTTP的，襪子analogx ， Wingate ，客戶等） ，蠕蟲/病毒具有內置的垃圾郵件引擎，和其他類型的木馬-馬功勳。 I was recently testing this list againt spam email.我最近測試這份名單againt的垃圾郵件。 Here are few observations from our testing.這裡有幾點意見，從我們的測試。

XBL is effective in catching comment spams. xbl是有效的在追趕評論垃圾郵件。 However I have also seen several false positives where genuine comments were flagged as spam by xbl database.不過，我也看到幾個假陽性的地方真正的評論被標幟為垃圾郵件xbl數據庫。 This is not surprising by itself.這是不足為奇的本身。 XBL includes list of IP addresses which are hijacked. xbl ，包括IP地址列表，這是被劫持。 However most of the time the owners do not know that their PC’s have been hijacked.不過大部分的時間，業主不知道他們的PC的已被劫持。 As it happens such owners also want to participate and make comments.因為它發生這樣的業主也想參加，並作出評論。 Working from a compromised PC doesn’t automatically make them spammers.工作從一個妥協的PC不會自動使它們垃圾郵件發送者。 However there is more to it that just that.不過有更多的給它，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.該xbl完全整合的數據從兩個高度信任dnsbl消息人士透露，與調整，由SpamHaus說，盡量提高數據的效率和較低的假陽性。 The main components are:主要組成部分是：
- the CBL (Composite Block List) from cbl.abuseat.org -跨灣連接路（複合砌塊的名單）由c bl.abuseat.org
- the NJABL Open Proxy IPs list from www.njabl.org. -n jabl開放代理服務器的I P清單，從w ww.njabl.org。

It appears XBL team is already working to eliminate false positives.看來， xbl隊已經工作，以消除假陽性。 The problem is that in many countries like India, IP addresses are mostly allocated dynamically.問題是，在許多國家，如印度， IP地址都是動態分配。 Many people also connect over dial-ups.很多人也連接撥號的UPS 。 Such users have a high likelihood of being identified as spammers with XBL.這些用戶具有很高的可能性被認定為垃圾郵件發送者與xbl 。 They are not necessarily using a compromised PC.他們不一定用妥協的PC機。

Note: XBL was not designed to catch comment spams.注： xbl的目的，並非要趕上評論垃圾郵件。 It was primarily designed for catching email spams.它主要是用來捕捉濫發電郵。 However the usage is valid because both kind of spams share many common characteristics and can leverage common technologies such as blacklists.不過，使用是有效的，因為這兩個種垃圾郵件有著許多共同的特點和可以利用的共性技術，如黑名單。 Both can be done manually and also heavily automated.雙方可以做的手動和也構成沉重的自動化。 Both are used to advertise same type of products.兩者都是用來做廣告同一類型的產品。
However there are differences too which needs to be kept in mind while designing anti-spam solutions.不過也有差別太需要，必須銘記，而設計的反垃圾郵件解決方案。 Comment spam is by far much easier to intercept than email spam in my experience.垃圾評論是迄今為止容易得多攔截比濫發電郵在我的經驗。

In Comment Guard plugin I have decided to remove XBL because of the false positives.在評論民警衛隊插件我已決定，以消除xbl ，因為該假陽性。 Comment Guard Pro is designed to eliminate false positives from comment spam detection (as well as false negetives).評論民警衛隊Pro是旨在消除假陽性，從評論的垃圾郵件檢測（以及虛假negetives ） 。 Any任何 source來源 of false positives, however valuable, is simply not acceptable.的假陽性，但寶貴的，只不過是不能接受的。
