Research is the intention, even in Splinterlands. That's why beakers too also offers a glimpse at the ingame-assets that the player owns, so a curator can do a quick research when the KE is high. And yes, it should be done for everyone. It doesn't cost anything to put the question under the post of someone: "Hey, I like your content, but your KE is really high. Would you mind telling me why?"
Something like that. I'd prefer people asking that. And if the answer is coherent, maybe it's even a incentive to vote higher, e.g. to support a person going through a financial struggle and trying to make some money in whatever way.
