I have the same thing that I at times stumble into accounts that have been here as long as me but I had no clue about them.
That said, find me someone who genuinely produces good content, engages with comments and other posts, runs a community, encourages engagement, delegates and encourages newbies but has a KE Ratio that is 10+. In nearly all cases, it all goes hand in hand. I also think there is a number of staked Hive where KE is not the issue anymore.
