How many posts i can publish everyday for a wordpress based video website?

Hello,
I want to start a video website and all videos will be from youtube.
so, how many posts a day are good enough not to get banned from google ?

I have never tried wp-mu, but If i setup wp-mu, do wp-mu work as a unique wp website ?
if possible i want to publish hundreds of videos each day. Please provide me a best possible way.

not more than 20...Better still under the 10 to be sure
