Nice follow-up!
The main point that I was trying to make is that there is a clear pattern (this isn't aimed at Curangel specifically, I just took them as an example). Go to any of the Curation Compilation posts, click on a random post that got curated, check the activity on the account and the wallet, and you will see in most cases that:
It just feels like many curators are taking a rather easy approach of having a list of accounts where they know the content at least looks nice to curate (or where they know more upvotes will come in on). While many of the content creators think that Hive is a platform where you post content and earn money which simply isn't a sustainable model if everyone is just cashing out and nobody is investing.
There really needs to be some awareness that if you want to get something, it also requires to give something, and Curation groups and their curators being aware, while at the same time raising some awareness around KE Ratio would be a good start.
In the end, it's fully the responsibility of those who make the upvotes or delegate their Hive Power to ones who make the upvotes. It needs to be near impossible for pure value extractors to do so. Also, I think Leased Hive Power should count toward KE Ratio.
