Hi Andy,

I don't remember anyone saying that all NXDOMAIN-generating queries should
be blocked.  Perhaps I missed that.  I believe the suggestion was to return
a specific record as a signaling technique for "high risk" names existing
under newly delegated gTLDs.

I'm also not sure what you mean by saying NXDOMAIN traffic is to be
expected and healthy.  Certainly we've known for years and years that
much of the traffic results in NXDOMAIN, so in that regard it is currently
to be expected.  But I think most people who spend time looking at the
sheer absurdity of queries coming in find it a bit depressing.
