It depends on the source of your traffic, not the ad networks. If you buy your traffic, you most likely need to match some advertising guidelines. Not all ad networks can do that, and even if they do it, there are flaws in this and it is easy to get fucked.
It is strange that JuicyAds is mentioned as top ad network for tubes - we are in the tube business since a while and haven't met anyone using them, in a mix or exclusively. :O
And this is not agains Juicy, I like them [used them on blog network a ~decade ago]
This is a sensitive topic, you need to experiment a lot, and these experiments cost a lot, thus you won't get a recipe on how to do this properly on this forum just because you are asking nicely.
