authority and "churn/burn" same adsense

I'm building a bigger site that I'm hoping to be a long lasting project. Until it is up and going I plan to do some "churn and burn" MNS sites to make some fast money. Will I risk anything if using the same Adsense account on all of these sites?

As long as you are not breaking their terms of service you should be ok.
Besides, do you have any other option?

I would not risk my Adsense account with churn and burn sites.
