I try to give much bigger upvotes to smaller accounts. For users bigger than I I usually give 5-15% , for users around the same size I give 20-60%. Smaller accounts usually get votes of 50-100% if I have the voting power for it. I’m not sure if this helps my own growth very much as I’ve never received 100% vote from a dolphin or whale but it spreads the distribution of wealth which is what I’m all about. Hopefully the big fish who know me don’t mind.
