My skepticism here is towards the distinctions made between push and pull.
If you look at the standard email transfer it involves a push SMTP
interaction followed by a pull POP interaction.

  And spam isn't a problem at the POP stage, other than it's
existence.  Spam is a problem at the SMTP stage, due to DoS, relay
attempts, etc.

In NNTP you have the same type of interaction but the partitioning
is slightly different. In effect you have the world pushing garbage
at your news server and then pull out the small quantity that you
are interested in.

  In SMTP, the sender can also request amplification of the spam, via
multiple RCPT TO's.  That's impossible in NNTP.
