Obviously the Spamhaus DROP list should be evaluated - you should not
use such lists unreservedly. That said, the Spamhaus DROP list contains
entries that *are* verifiably bad, e.g. the well published Cernel prefix.

Regarding the extraordinary claim - consider the possibility that Nanog
has its share of kooks.
