Porn trailers on YouTube?
 

I keep finding porn trailers and teaser clips on You Tube (packed with porn kewyords in the title and description) - they don't show nudity, like the first few mins of a porn video or solo girl shoot. I'm guessing this is against their terms but its not actually showing porn. I'm wondering, is this a legit way of getting traffic from Youtube? Does it work?

It's probably working quite well but those videos won't last long on YouTube.
