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?
And with your last statement, clearly Prom is talking about BlockNET, he's just trying to make himself seem like a much bigger and important player in the industry than he really is, BlockNET was initiated by Dan, not prom. BlockNET will be a team of devs when all is said and done, although dan will be coding the basic protocol for it.
Okay, so assuming Prom was talking about Blocknet. Then no matter what Prom's role is in Blocknet, he was still included in the project. You're really okay with that and don't see anything wrong with it?
