While I agree that the (at least temporary) mitigation of the threat was overall a good thing, I'm not really happy with the method used.  Decisions to drop/block/filter traffic should be done locally.  I would have appreciated Talos coming to the various *nog lists and saying something like "Hey, there's some really bad guys here.  Here's the evidence of their bad behavior, you really should block them."  That probably would have had a wider reach than just going to Level3.
