You are correct. What Amazon disallows:

Offensive Content. Content that is defamatory, obscene, abusive, invasive of privacy, or otherwise objectionable...

They give examples of child porn, etc but those are an incomplete list.
They may:
investigate violations of this Policy or misuse of the Services or AWS Site; or
remove, disable access to, or modify any content or resource that violates this Policy
