Woke up this morning to find 116 notices of trackback spam littering my inbox. Out of the blue, and I notice that a whole bunch of other weblogs got hit today, too. It appears some spammer finally wrote a script to exploit trackback. Ah, well. It was easy enough to fix; do a quick mod to my add_trackback.php file, redirecting bad traffic, and a quick SQL query on the database to clear out the offending spam, less than 10 minutes. Gotta love having absolute control over my system.
