The real solution to the scorched earth problem is for aging from blacklists to be dynamic. If a given IP hasn't spammed or otherwise been naughty in some period of time, and the RP contact information for that netblock exists and responds, then the benefit of the doubt should go to the neblock owner/operator, and the IP(s) delisted. There's been some work done @ SRI on using a weighting algorithm that includes things like prevalence, persistence, and "badness", with a Gaussian decay function as to time, to establish cut levels for what should be blocked. Look at Phil Porras work, and Usenix presentations.
