One approach to identifying a destination for spam reports is to inspect
the RECEIVED headers of the suspect message and fire the report back to
the last MTA (or perhaps a DNS txt 'spamReport' record assigned to that
MTA).  This assumes that it knows what to do with it, possibly leading
to a cascading effect.  IMHO, this is a good way of getting the info
back to systems/parties that we expect to block it.  

One potential hazard is the reports being cascaded back to the spammer,
or otherwise exposing the reporters to the extent that list washing
would be possible.  Another conceivable undesired effect is a single
spam message generating a large  number of abuse reports (if an MTA fans
out reports to multiple destinations) causing capacity issues.
DOS-by-spam-report isn't what we're after.

Not sure how practical this would be.  It would be a challenge to get a
critical mass to adopt.
