I thought that @emmanuel50 fits your requirements. He has been on Hive since 2025 and is growing his stake instead of powering down. But then I checked and it seems that he sometimes posts twice a day.

Maybe I could fit as well? I mostly make posts about my art. Those posts often have 1 or 2 photos of my current pieces and maybe a few sentences describing my progress. So I am not sure if that counts as high enough quality. Also my current art piece is about Hive and I will still have at least 1 post about it in the future. So maybe that counts as talking about Hive all the time. I also make some long form posts as well. Usually they are about games I am playing. My KE is decent (0.43) and I plan to be here till either I will die or Hive stops working. I assume that neither of these things will happen in the next 5-10 years.😛

Also, I'm mainly looking for users who are underrewarded so the ones where the average total daily post payout is below 10-20x the value of their own upvote value.

that being said this rule may be a problem and disqualify me. Some of my posts(mostly gaming posts) earn a few dollars so they could push my average rewards above your desired averages.
