---- Examples of URLs after "unnatural links" warning not in WMT

Has no one received examples of links that "violate the Google quality guidelines" that are not in their backlinks in webmaster tools?
I did get a sample of bad links at some point but I cannot recall if any or all of them were in the WMT list at the time. But that does not matter: the fact that you did get a sample is so rare and unique that adding yet another qualifier (asking "are they in your WMT?") makes me think that the answer to your questions is (almost) a guaranteed NO.
By the way, the samples I was given were a toss: one was bad (though not spam and I had no idea these links were bad at the time) and one was a benign blogroll link from a totally relevant site of a buddy of mine. Still, the email from G helped to establish some line of communication, thin as it was, and did lead to some improvements (which had, sadly, been reversed since then).
