Why my youtube's google rank keep dropping after backlink?

I am kinda new in video marketing, so I just tried out youtube. I waited 24 hours, it has finally ranked. But it is on page 5.

So I blasted 1000+ backlinks to my youtube, then today my vid dropped to page 9? Why? I read some ebook and thread, they said youtube vid will not get penalized??

This is weird. The more I blasted backlinks to it, the more its dropped...anyone knows why? May be too early to blast the backlinks?

I do use vagex and enhanceview at 1st day to look natural first.
