If all those hours have been flown - not sure how you know who did what and in what conditions - then they were probably over well-lit enough areas to give adequate orientation, as the rule requires.
But, if they did that without being able to see the ground, then they did not fly in accordance with the rules for night VFR - simples.
Do tell how you control your pitch and roll attitude in an unstabilised aircraft without an external reference if you don't have an AI and you can't see the actual horizon. Perhaps the ubiquitous i-pad?
