I don't see any 'nofollow' in their external links, which is a good thing.
_Ex: https://www.moneymagpie.com/make-money/how-to-make-money-as-a-prison-consultant - search for the prisonconsultants domain and use inspector to see the source code. _
Spam scores for this site is also low (1%) so I don't think you would be penalized.
From a tracking perspective, you will not see traffic attributed to the referrer because of the rel="noopener noreferrer" tag in the anchor ref, so source will show as 'direct'. I think it would be a good experiment. Let me know how it goes if you do end up doing this, may use for some of my clients as well.
