you allowed to post music videos from youtube to your facebook page

[c=BF0080][i]i got a couple of notices from youtube in the past few weeks, that i posted content which violated the rules...i can't recall what it is i posted as i've never posted anything dubious, just nice nature/animal pictures.......but i did post the odd music video from youtubs so i'm wondering if it's this which violated the rules?

does anyone know?[/i][/c]
