One of my low-traffic sites was hit with significant trackback spam. We found out when we were notified by our hosting provider of a significant bandwidth overage for the month.
The spam module was doing a great job of keeping the spam out, but due to the flood of trackback requests during a sustained period, we experienced a massive increase in traffic.
I have now disabled trackbacks on that site (ti's the only site I had set up to allow trackbacks) and have enabled the spam module's "Trackback Black Hole" module so that all trackback requests are dropped immediately.
Keep an eye on your server logs and traffic patterns, people!
