Have often wondered about this in terms of some of their control plane APIs, a read-only IAM key used as part of C&C infrastructure for a botnet might be interesting, you get DNS/ClientHello signature to a legitimate and reputable service for free, while stuffing "DDoS this blog" e.g. in some tags of a free resource. Even better if the AWS account belonged to someone else.
But certainly, ability to serve an unlimited URL space from an account with only positive hits being billed seems ripe for abuse. Would guess there's already some ticket for a "top 404ers" internal report or similar
