Indexification For Tumblr Indexing

I have indexification and want to use it for indexing my registered expired tumblrs, I have already added 5 posts to tumblrs with spun content, and pictures, followed some people and changed theme. I pinged it with free service, so I have indexification how many links should I send at 50 per day? 100? drip feed? Or just blast it? Any other ways to index all my web 2.0 tumblrs?

If it doesn't link out to MS yet and are not connected, then doesn't matter much, otherwise do it drip fed few per day.
