Links from a set of websites - How Safe?

Hello,

I am thinking about using a set of websites for guest blogging to build links to different pages of my money site (MS). Something like

Guest post 1 on Site 1 -> page 1 from MS
Guest post 2 on Site 1 -> page 2 from MS
Guest post 3 on Site 1 -> page 3 from MS
Guest post 4 on Site 2 -> page 1 from MS
Guest post 5 on Site 2 -> page 2 from MS
Guest post 6 on Site 2 -> page 3 from MS
Guest post 7 on Site 3 -> page 1 from MS
Guest post 8 on Site 3 -> page 2 from MS
Guest post 9 on Site 3 -> page 3 from MS
Guest post 10 on Site 4 -> page 1 from MS
And so on...

So, I am talking about different guest posts on several partner websites (around 10 sites) with links (long tails, LSI etc. anchors) pointing to different pages from my Money Site.

This might be a good way to spare some money and outreach effort by better using current partnerships, but it looks a little like a PBN to me.

However, should I expect any trouble using this pattern? Is it useful, or worse, harmful?

Thank you very much.
