CNET Suffers from Trackback Spam

Jason Dowdell says that CNET News.com is being pelted by trackback spam and he wonders if any of the bloggers are actually generating any traffic from it. I have trackbacked CNET a few times and have seen nary a click through in my server logs. Perhaps it's because CNET doesn't list its trackbacks right underneath the news stories, but on separate pages that garner few visitors.
