Despite the obvious ability of people to predict who is who by writing style, theoretically you can't know for sure who it is, so if you guess right, it doesn't matter because you can't know if you are right.
We don't have that many people on this forum. And if each person guesses someone different, and the author must reveal once discovered they will eventually uncover the real author in only a few tries. On the other hand if there is a waiting period each member can guess several times and debate with others, and actually have fun reasoning out a conclusion before it is revealed.
And I don't think it is fair that the author can't post about their own post nonanonymously because it makes it much more likely that they are the author if they dont participate.
So if the point of this game is to reason out who is who just on the basis of the ritual itself, there are several things undermining that if one, there is no set waiting period, and two the author can't join in on discussion.
