well it is pretty interesting that Google has developed a system in which they create free editing by humans to help tell Google which links are good and which links are bad. So if you want to be in the Google index or rank you need to go through your links and tell which ones are bad and help Google with the editing in this way.I have to admit its pretty ingenious on Google's part. If it is going to work to the advantage of Google and make their search results better, I see plenty of reason for them to pursue this strategy. That said, there are parties that have interest that run contrary to this and an industry that crops up that actually creates the bad links and monetizes that is a likely scenario.
