Prom was probably an ethical business person when it came to negotiating terms for code reviews. Thats what it means to be ethical if your doing business with someone. Do you really think he has the time to read over Prom's post history and see if he is an ethical poster?
So negotiating to have Dan code review Hal while he was not an unbiased 3rd party and giving everyone else the impression that he had nothing to do with Hal, was ethical?
