Yes, people have had their sites displayed related to YouTube videos, just because it is on the YouTube site doesn't mean the video complys with AdSense TOS or its policys.
2 of my sites was banned even it was hosting youtube video but adsense does not allow video which you cant watch your parents or kids(rep wrote me this 2 times)
My Video website has been banned last week. I don't know why. Google banned my website after I submitted sitemap.
