yes there's no perfect system, I can agree to that. However, I feel to have a sustainable ecosystem and looking for long-term to prevent issues like you said about the blatant extractors, KE Ratio is a better evaluation as it's taking in more factors and I think it's a system that can still be improved upon. What we are seeing now is just the beginning.
Activity needs to be measured as well. I just don't find join date to be a good evaluation because there are some people here that came from splinterlands. For example, I am one of them. My join date is Jan 2022 because that's when my hive account was created for my Splinterlands. i actually never interacted with the blog side of Hive until maybe Dec2022 if I'm not mistaken and probably didn't actively post until feb/april 2023 hence the hp vs join date can be quite flawed in this case.
I know everyone likes things fast and easy now especially in our current times aka super short low attention videos (tiktok) but I don't think it's the way. Let's put some more effort into making a better system yeah.
Who knows maybe they will incorporate a way to factor in join date to the ke ratio as long as it was a fair measurement, I wouldn't mind.
the KE Ration is probably better but it takes longer to check and it excludes delegation for as far as I know
oh and with ai and coding. this can easily be fixed and improved over time. the speed to check. If I'm not wrong
