A varying but significant percentage of the reported posts results in no action because the slight observed by the person submitting the report was considered negligible by the staff.

I do occasionally make predictions despite having read the manga. They are what I remember thinking or hoping back when I was reading that point of the story. And usually more or less wrong... I omit any such "predictions" if they are correct unless they are so obvious that only a monkey wouldn't see them coming.

But then again, I clearly don't take Internet nearly as seriously as you do.
