Why are there no "Mary Sue this" or "Mary Sue that" threads here?

Why are there no "'Mary Sue' this" or "'Mary Sue' that" threads on this Women and Film board? In a way, I'm glad that there aren't, because since the beginning of this year, the term became popularized and not before long Web trolls got a hold of it, and now it is a meme. (And I'm sure you know which particular film elicited the fiasco. If not, then take a wild guess.)
