o.o I'm actually almost half-surprised there isn't a tracker. (Er, like an issue tracker for moderation, not the conspiracy theory version, which I assume would be a chip in the arm or something)
Though upon reflection I shouldn't be. My vague feelings of "it would seem beneficial" (for communicating among mods, not tracking undesirable) aside... Even if that were true, someone would have to write that code and maintain it. ~.~
