wp mu

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...

I tried searching and couldn't find anything on this, but lately I've had some success using Google to hunt down WP MU blogs and create some backlinks. Search term: inurl:"wp-signup.php"So for one of my Music niche's I did a search for that with +music attached. Found like 5-6 good networks...
