I agree that forgeries are a major problem that must be handled.
However, we are dealing with a system that does not allow for
electronic signatures.

I did not write any of the net news software, but perhaps those that
did would consider this option:
   In a future release of the software add a check that each site when
   receiving forwarded news check that the site prior in the path
   matches the forwarder.
This might also have holes and be possible for the forger to add a
message that seemed to come through them to the new site.  I only
offer this incomplete suggestion to further the discussion on how
to avoid this going to a full public key encryption system for posting
messages as that would be too much overhead.
