Lists details of the last 100 trackbacks on the page of the Trackback Validator plugin for WordPress.

For the last 100 trackbacks (starting with the most recent), it lists the timestamp and whether the trackback was marked as spam. This information can also be found under the "Recent Activity" heading, but you have to mouseover each red/blue tick mark to see each timestamp. This user script should make it easier to see the timestamps at a glance.

Trackback Validator is developed by Rice University's Computer Security Lab, which I am in no way associated with.
