I like your pro-active initiative. IMO, it's the search engines that need to combat this. Your list will only help them. It will give them links to their articles. Also, take into consideration that they will be able to post new content and new sites faster than you can make a list that will not have any impact on them. There are ways to game the Google SERPs. Google has caught on to most link spamming, duplicate content, link bombing as well as artificial links.
There will be a cat and mouse game between online spammers and google until AI can distinguish spun content and spam. That is until spammers have their own AI.. Sounds like a war. My bet is on Google.
This reminds me of a video I saw on youtube about AI learning to walk.
