Actually, that is exactly what you did.

True (and rather obvious).  Here's another obviously true statement:  
As more & more spam comes from a set of IP addresses, it becomes less  
& less likely you should accept e-mail from that space.

Not news to anyone who works on anti-spam or e-mail deliverability.   
Perhaps the collateral damage will force Amazon to get things fixed  
faster.

Or maybe not, but either way I don't see how you can blame someone for  
not wanting to accept e-mail from EC2.
