Suggestion: when you spot broken links like that, create redirects so that they start working. Use 301's preferably, that send both the user and the link juice to the "real" page.
Thanks for your suggestion. Actually, I've considered doing re-directs for these already. But most of them are low-value backlinks from forums, usually with nofollow tags, and I want to keep all my sites "clean" by using as few re-directs as possible. If I ever see any high-value bad links, then I probably will redirect them.
