A friend sent me the following:

This seems to be the first one by McIntyre himself:

Anthony Watts claims to know the identity of the mole, calls him/her "Deep Cool"

Then a few days later on CA:

And on WUWT:

That's as far as I got.  Kind of gives new resonance to the concept of whack-a-mole, doesn't it?
