Hi,
 
Thanks a lot for sharing.  Just read the article titled "Make Easy Money from Your Parked Domains with Google AdSense for Domains". 
 

https://www.groovypost.com/howto/google/google-adsense-for-domains-review-make-money-from-parked/               

 

This article by Google itself teaches you how to make money from parked domains, although at the expense of consumers and end-users.
 
I am used to think of Google as "DO NO EVIL".  Well, maybe not always ...   :(
