Last October/November, I built a statistical trackback spam filter called Snark. It worked very well, blocking about 99.8% of spam without requiring any attention from me, until its data files got wiped by accident during the DDOS attacks last month.

Last October/November, I built a statistical trackback spam filter called Snark. It worked very well, blocking about 99.8% of spam without requiring any attention from me, until its data files got wiped by accident during the DDOS attacks last month.
When I got Snark up and running, we were getting on the order of 10,000 trackbacks per day. Almost all spam, obviously, but Snark made short work of those.
In May, the last full month of Snark operations, we received nearly two million trackbacks.
So far this month, we have received four million trackbacks. It's gotten so bad that at the peak of a spam flood, just firing off a CGI script to log the requests was enough to melt Apache.
