IMHO, Amazon will eventually be forced to bifurcate their EC2 IP space
into a section that is for "newbies" and a section for established
customers. The newbie space will be widely black-listed, but will also
have a lower rate of abuse complaint enforcement.
The only scalable way to deal with a system like EC2 is to provide clear
demarcations of where the crap is likely to originate from.
Or, more likely, two separate companies will tackle the problem... Ala
Ironport or similar.
Some clusters will provide a high degree of trust and certainty of the
activities of its customers, and some won't. There is no reason to
believe one company will do both equally well.
