That sounds perfectly normal to me. What is your question?
I agree that it's time for a coherent and publicly articulated policy. And email notifications of change of status are long overdue. But post slugs on tag pages CAN be misleading: just yesterday I reported as mature a blog that had inoccuous text and images in the first paragraph and hardcore porn in the second as a default; this appeared to be gaming things so it wouldn't be reported for how it was showing up on the tag pages. But email notification would help all sides of the issue: it would prevent befuddled and embittered bloggers wondering if no-one loves them, it would give them a very clear understanding of what was over the line, and it would enable them to choose whether to modify their posts in future and un-Mature their blogs, or to continue as a mature blog.
