Backscatter is far less common than years before because most of the  
spam today is spewed out by queue-less bots and not open relays with  
real MTAs as it was some time ago. The receiving end does recipient  
verification most of the time, so at that end bounces are not created  
either.

With this, the amount of backscatter is declining more and more IMHO.
