Nobody's saying that the root servers are responsible, only that they
are the point at which these domains would have to be squelched. In
theory registrars could do this, but some would have a financial
incentive not to. Also I don't believe registrars can update the roots
quickly enough to be effective (correct me if I'm wrong).

Given the obvious differences between legitimate fast flux and the
pattern/domains in question it would seem to be a no-brainer,
technically at least.
