++added:
Other ideas:

 * Resource usage: maybe block abusive dumb spammers (e.g. more than 20 failed 
attempts) for 48h

  * Beware: if a harsher blocking behavior is detected, dumb spammers may 
improve their software; try to make it stealth

  * Beware: be lax with blocking, false positives are easy (shared connections 
with a single IP, etc.); keep the threshold high. It's just for efficiency, 
those plain spammers are already blocked.
