Very interesting suggestions. You write about things important to me. Sometimes I check the history of the user's behavior, some of them I just remember because they regularly do things that I do not accept. And sometimes I just don't have enough time for it and then I don't give upvote or downvote.
Such indicators would be helpful. There are, however, issues such as tipu for tipu and vote for vote. Another - producing original content, but very low effort, like a completely ordinary photo without any keywords, a video of some activity in one game or another (nothing special, no one watches it later), two sentences plus some "sensational" photo or video found on Reddit.
And finally publishing posts on several blockchains. It's a simple poolrape and spreading too thin.
Some users do not understand, or pretend not to understand, that such behavior reduces the value of Hive. If you rely on their words, you will read that they are perfect users, produce great content, pursue their passions, are great tip curators and the downvotes on their content are completely wrong.
