I think you are ignoring a very obvious fact, those 1% that are no longer 'complaining' are really doing so in an automated fashion with their blacklists. Further I think the complaints will be even better because people are more inclined to a fix a problem if it is easy to do so (adding it to their blacklist) than sending an email saying please remove this from my search results (and hoping it gets removed in the future), or doing an ad-hoc in browser solution that does not give feed back to google.

What I think really needs to be exploited is a ring of trust type aspect, I'd like to have the Hackernews ring where all us on here work together to remove the spam from our results and let's Google see what are taking out, maybe that will help them improve their algorithms.
