For sure am not a moderator but my observation by giving out good/bad reps was there was not any more discernable change in posting by the receivers than before.
I would say that much like police forces who notice a rise in crimes during a full moon the full moon has more effect here at FT on the attitude of posters than the reputation feature did.
But that is my opinion of seeing probably a smaller part of FT than you and we all know that refs can not see. But I will tell you that there are always more fouls in games during the full moon.
