Trackback Validator Plugin
Introduction
The TrackBack Validator plugin for WordPress performs a simple but very effective test on all TrackBacks in order to stop spam.
Legitimate TrackBacks are sent by people commenting on your weblog, accompanied by a URL that points to that commentary. Spam TrackBacks are accompanied by a URL that points to a pay-per-click affiliate website or other irrelevant material. The Validator exploits this key difference:
- When a TrackBack is received, the plugin retrieves the Web page located at the URL included in the TrackBack.
- If the page contains a link to your weblog, the TrackBack is approved.
- If the page does not link to your weblog, the TrackBack is flagged as spam and rejected.
Because TrackBack spammers do not set up custom Web pages linking to the weblogs they attack, this simple test will quickly reveal illegitimate Trackbacks.
We are actively developing additional heuristics to add to the plugin; if you observe TrackBack spam that makes it past this plugin, please let us know.

Downloads
- TrackBack Validator Plugin v0.7.1 (ZIP)
- Older versions: v0.7, v0.6
Installation
Prerequisites: You need an installation of WordPress version 1.5 or later.
- Unzip the trackback_validator_VERSION.zip file; it will contain the file README.txt and the directory TBValidator. Move TBValidator to your <wordpress-directory>/wp-content/plugins directory.
- Using the WordPress administration interface, turn on the Validator from the “Plugins” page.
- The “Options” page will now have an additional tab, “Trackback Validator,” which allows you to configure the plugin and to see a graph of recent trackback classifications (see the screenshot).
Changelog
- version 0.7.1 [21-May-2006]
- Fixes a bug with WordPress 2.x blogs.
- version 0.7 [17-May-2006]
- Removed problematic dynamic link page detection. (Additional research will tell us what exactly we need to look for in order to defend against dynamically generated spam sites; since we’ve never seen any of these in the wild, it’s not currently a high priority anyway.)
- Improved the robustness of data reporting. Reports now use an HTTP POST interface and will submit data to trackback-db.cs.rice.edu, rather than a fragile IP address (!). Data reported by our users is crucial to the research process; see our forthcoming technical report to see how this data is used.
- Fixed the trackback history graph. It would silently fail on hosts without GD installed; the new version doesn’t require GD at all (and is therefore a lot simpler).
- version 0.6 [announced 19-Nov-2005]
- Added a simple check against spammers’ dynamic link pages.
- Simplified the data submission routines.
- Set up framework for PageRank comparisons.
- Cleaned up code.
- version 0.5 [announced 24-Aug-2005]
- first iteration
A plea for help
This is the subject of active research by the Computer Security Lab at Rice University. We ask you to enable the “Submit Data” option, to send data back to us for scholarly analysis. You’re free to use this plugin without reporting data, but your data is important to us as we attempt to understand the evolving attack profiles of weblog spammers.

I knew Dan online back in middle school, so with this endorsement, I installed it instantly: The Computer Security Lab at Rice just released the first public version of the Trackback Validator plugin for WordPress blogs. Since I’ve been using it, I’ve had 100% classification accuracy on Trackbacks (read: every legit Trackback makes it through, not a single spam Trackback). Maybe Trackback isn’t quite so dead after all. […]

[…] It’s a simple concept that I’ve seen implemented at the Washington Post blogs. It basically validates IF there is a link to your site in the post that’s “tracking back”. It’s called Trackback Validator Plugin and should work for anything around Wordpress 1.5 and up. Akismet looks to be available for other blog/cms as well. If you’re using another cms I’d look into a trackback validator. In theory, this should stop the rest of the trackback spam and likely take a bit of the load of akismet, because I would think it would filter things out before they get to akismet. Testing it on this site right now, will add to the others later. […]

The Trackback validator will check the referencing URL to make sure that it is a legitimate trackback. So, I have turned off the requirement to register in order to comment, you may comment at will!

[…] Nos últimos dias (mas muitos) o meu blogue tem sido invadido por SPAM, aquele termo informático que muito directamente e sem deambularmos, significa LIXO. Não é que vocês o vejam, na realidade não vêm mesmo, todo ele fica retido e é sobre essa retenção que quero falar um pouco. Habitualmente o SPAM é feito de uma maneira muito básica, constroem-se robots de net que correm determinadas sequências de programação e atacam x alvos em rodada e de forma agressiva. Como não é novidade nenhuma o Wordpress, motor que uso na minha página pessoal a partir da sua versão 2.0 veio equipado com uma coisa chamada Askismet que reduz bastante esse tipo de lixo, no entanto a moda do SPAM expandiu-se e além dos habituais comentários, ataca agora também os Trackbacks e é ai que o Askimet me estava a falhar um pouco, em 15 deixava passar 4, que mais tarde tinha que eliminar à pata, dessa forma e porque fazer tal tarefa todos os dias é cansativa procurei por um complementar ao SPAM para o WordPress e foi assim que achei o Trackback Validator Plugin que é bastante eficaz e que recomendo a quem sofra do mesmo mal.

[…] Trackback Validator even thoug being a nice plugin that kills trackback spam, always emails you every trackback (even the filtered spam ones). It’s working very efficiently to me, anyway. There were two little issues with this plugin: until version 7.0, message counters in your blog were not correctly updated (instead, the plugin manages the WP database directly) and spam trackbacks are also mailed to you (so you might end up mail-flooded with spam as I did). This is the code related to this issue (at line #138 in file trackback_validator.php): <?php if(tb_run_checks($tb_info, $permalink)) { $tb_type="ham"; if($tb_options[’auto_approve’]) $wpdb->query("UPDATE $wpdb->comments SET comment_approved = ‘1′ WHERE comment_ID = ‘$comment_ID’"); } else { $wpdb->query("UPDATE $wpdb->comments SET comment_approved = ’spam’ WHERE comment_ID = ‘$comment_ID’"); $tb_type="spam"; } […]

Hi. I just installed this plugin but I get an error for the SPAM table:
DROP TABLE IF EXISTS `wp_tb_spam`, it does successfully create the wp_tb_data table though.
I deactivated the plugin, dropped the data table and started over but same results: the spam table is not created.
Any ideas? TIA.

What error do you get? Does it prevent the plugin from working correctly?
The `wp_tb_spam` table is used by an older version of the plugin, so it’s just trying to tidy up.

Gegen Trackback-Spam habe ich das ebenfalls von Michael empfohlene Trackback Validator Plugin installiert. Es checkt, ob der Spammer einen Backlink in seinem “Text” auf mein Blog gesetzt hat. Echte Spammer tun das nicht. Obwohl es mittlerweile findigere Spammer gibt, die via Tricks den Backlink tatsächlich einbauen, danach aber wieder rausnehmen.

Kommt ohne Datebank-Zugriffe aus. Klappt bisher perfekt! Kein Kommentarspam mehr. Die Datenbank wird geschont. Wehrt natürlich nicht den Trackback-Spam ab. 2. Spam Karma komplett aus wegen zu viel Last 3. Akismet ebenso aus Lastgründen deaktiviert, wird aber zeitweise aktiviert, um den Trackback-Spam zu entfernen, der sich angesammelt hat. Zumal sich dort hin und wieder false positive TB Spam verfängt. Nach dem Löschen der Spameinträge wird Akismet wieder deaktiviert. 4. gegen Trackback-Spam habe ich den Trackback Validator eingebaut. Der läuft wie das Math-Plugin ganz ohne eigene DB-Tabellen. Blockt TB Spam so, dass es nicht in den Kommentaren angezeigt wird. Kleiner Nachteil: Da ich bei jedem neuen Kommentar bzw Trackback eine Mail bekomme, erhalte ich nach wie vor auch eine Mail, wenn TB Spam eingeht. Ist aber zu verschmerzen, da man das in einen Mailordner automatisiert via Mailregeln wegfiltern kann. […]

In den letzten Tagen war mein Layout im Internet Explorer zerschossen, worauf ich allerdings erst hingewiesen werden mußte (Danke!), weil ich ausschließlich Firefox verwende. Nach längerer Suche konnte ich das Problem identifizieren: Lange URIs in den Kommentaren, die durch GetRecentComments angezeigt wurden, waren Schuld. Dieses Plugin ließ sich auch wegen einer seltsamen Fehlermeldung über die Redeklaration der Funktion kjgrc_subpage_exclude_cat() nicht mehr konfigurieren, aber in einem Forum fand sich dafür eine Lösung. Danach war es natürlich ein leichtes, die Einstellung zum Umbrechen langer Wörter anzupassen, auch wenn ich zunächst erfolglos versucht habe, hier den LinkTruncator zu verwenden. Weil ich gerade dabei war, habe ich auch noch den Trackback Validator installiert. Der nervige Trackback-Spam hatte in letzter Zeit doch etwas überhand genommen. […]
