No this is not a thread to encourage spam, but rather to fight it
ACMA has implemented the SpamMATTERS reporting and forensic analysis system to help fight spam. A SpamMATTERS reporting ‘button’ is available for download and installation into the Microsoft Outlook and Outlook Express email programs. Once installed, users can simultaneously delete their spam and report it to ACMA with one click of their mouse.
Spam reported using the button is forensically intact and contains the information that ACMA needs to track down spammers and take action against them.
You can also report manually if not using Outlook (Lookout) express.

A nice step forward
