I can't tell whether I'm getting spammed or whether the Google bot has been hijacked, or is bing imitated. I've been getting trackbacks all day, on a limited number of posts, that all have something like "Good Information Good Information...", where the second one is a link to Yahoo. The puzzling thing is, by examining my logs, they are all coming from the Google bot - at IP address 66.249.72.104. Running traceroute verifies that the IP in question is from Google; so why the heck am I getting trackback spam that leaves a link to Yahoo from their bot? Very strange.
