Wordpress: Trackback Validation Plugin for WordPress
Simple Trackback Validation Plugin for WordPress 2.0.x and 2.1 performs a simple but very effective test on all incoming trackbacks in order to stop trackback spam.
How it works:
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 blog, the trackback is approved. But if the page does not link to your blog, the trackback is placed into the comment moderation queue (or optionally marked as spam).
Since most trackback spammers do not set up custom web pages linking to the weblogs they attack, this simple test will quickly reveal illegitimate trackbacks. Also, bloggers can be stopped abusing trackback by sending trackbacks with their blog software or webservices without having a link to the post.
