OK. I don't think this is the solution you're after if your problem includes "crowd sourced video".
Nudity detection though - I'd probably at least try doing something like "Check every 50+rand(100) frames, and only examine more carefully if you get hits on that sampling". Sure - that's "game-able" - but subliminal nudity isn't something I'd expect trolls or griefers to expend too much effort to slide past your filters...
