I began adding blocks when users complained about tasteless ads. Following Jenstar's advice, I removed the blocks (40 of them). Since then, I have seen a CPM increase. Perhaps when AdSense was new, site visitors were more easily alarmed by what they saw as inappropriate. Now, maybe they are better able to distinguish ads from site content and I'll see fewer complaints.
