I am amazed that you looked through the source code of the page. It seemed like a pretty bland/generic site to me, not worth checking out what's going on under the hood. Good find though.
Nah, I found it because I generally browse with Firefox + NoScript which disables most javascript, including the little snippet that this spamblob uses to hide itself with css. So it appeared black and bold in the middle of the page footer :)
