Notice two things: the spam message is included in H1 tags, and as a result it's extra-obnoxious, because it's very, very big. Spammers like to use H1 tags because Google and other search engines give words in those tags much more influence.
I tried getting Spamlookup to junk any link that included an H1 tag, but despite having told the plugin to junk anything with the string "<h1>", the spam kept on coming.
