No, there's nothing in the AdSense terms/webmaster guidelines that mentions your backlinks. Bans usually come from sending traffic, fake clicks, poor content and ad-stuffing.
No, I mean I want to put adsense on my moneysite and then buy PBN links that have spun articles on them.
Its a good idea having Ad-sense in your money site. But, i don't think why would you pick links from spun network. There are some other methods to do like web 2.0, social bookmarking etc.
