Admin CP -> Applications -> Display Node Tree -> [click the forum] -> Moderate all messages posted in this forum
Admin CP -> Users -> List User Groups -> [click the group] -> Follow message moderation rules
My guess is that the group permission is set to Never for one of this groups. Never is overriding and would result in his posts being moderated no matter what. Not Set is more appropriate for promotion setups.
