Indeed. It almost makes me question whether this was a real 9 year old, or a teacher that wrote lower than their level (but not low enough) and that was outraged by the activities ... and then signed it their child's name.
I get the impression from reading it that it's her content but her dad is doing the editorial for her which, given it's a 9yo with a blog, I'd call pretty sensible parenting.
That's a reasonable and less conspiracy-esque theory. It seems more plausible than my idea -- though it wouldn't surprise me if a teacher actually did do that.
