Those are all good ideas. Do you know if spammer links do get deleted? How do the folks who maintain the sites find abusers or bots?
Wikipedia tends to find them eventually. Sometimes, spam links can live on a page or two, so higher count links are going to be safer. Also pages that get updated a lot (and the link stays for each revision).
Also, while DMOZ might have some spammer links, I suspect most of the spammer links are very stable, well-listed in SBL and your blacklists, etc. It might be easiest to prioritize links by their S/O ratio:
(number of blacklist source hits) --------------------------------- (number of whitelist source hits + number of blacklist source hits)
