"Is it acceptable to IHUB for a moderator to receive outside compensation for a company they moderate?"
Yes. In fact, off the top of my head, I know of at least one really good Moderator who is a promoter for the company of the board he moderates. The board has a lot of dissension and rarely is on the TOS Report and I've seen very, very few deletion review requests for the board.
"So my question stands - thanks for the opinion, but I want a ruling...."
Dave has already replied twice. If you want to hear from someone specific, then I'd suggest a pm or a reply to one of their posts.
