We've come to think of spam as having a commercial motivation, but the term first came into being when somebody wrote a program that would post the word "SPAM" over and over on a newsgroup. A reference to the Monty Python song, the chorus of which goes "SPAM SPAM SPAM SPAM...".
You've got a 1,160-page thread going that (I assume) contains no useful information. Just a lot of redundant text. Spammer or no, it's a semantic distinction.
Based on the definition of lots of words nobody needs to read, one could argue the case that the entire CH subforum could be labeled as such. And as the king of the Coffee House, bapu, that would make you the king of Spam.
