> becoming harder to shut-down as they can spin up instances more easily and get going from a new location more quickly I don't think this is going to work in their favour - spammers already have the tools they need - the real killer is blacklisted IP's/ranges. If you're legit, you can jump through some hoops if you inherit a blacklisted IP. If you're a spammer, all you can do is try to get an IP that isn't blacklisted.
