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)
