Never did it in 10 years with AdSense. In fact the review center is a by-request feature, so I've just requested it for the first time.
There's still a question in my mind though: AdSense is supposed to be an intelligent system that optimizes ad serving for you (and for G, of course). So, wouldn't too much of manual input actually hinder the optimization algo rather than help it?
Also, presumably that does nothing to interest-based ads, right? So, is the review only effective with interest-based ads OFF (which I don't even know for sure if it's possible to turn off anymore)?
