[Operators] How-to fight with SPAM accounts

[Adam Seabrook]

I have not been reading all of this thread so I apologise if this has  
already been raised. Why not just set up something similar to www.senderbase.org 
  where we all report the number of messages received from each server  
and each account. Any server or account that has an uncharacteristic  
increase in messages can be blocked or flagged to the server operator.
