Might I suggest adding one extra behavior? Once an IP address follows a nofollow link, from then on *any* link serves up the /nonsense/ version, so they don't even get to learn from the real articles and AI isn't given a larger data sample to learn that the difference between the real articles and the fake ones is the /nonsense/ in the url.
