Question about Multisite and Adsense

I've been thinking about creating a multisite and placing some Adsense ads on it in hopes of generating more overall Adsense revenue. But, I'm wondering if having a mass amount of blogs (for example 50) within multisite would be against any of Google's/Adsense's terms? Could this in any way put my Adsense account in jeopardy?

Also, would interlinking the multisite blogs be considered a PBN?

Thanks
