I am not particularly well-versed with regard to the intricacies of Hive tokenomics but my proposal is simple and sounds like this

1. Payouts would still be on a 7-day window but refresh on the same day eternally albeit at a diminishing rate, not for the same curators to upvote the same content over and over again but for those who have not seen it yet

2. Further technical brainstorming is required for this so my suggestion is open to improvements and criticism. Metadata will be attached to every delegation thus preventing an unnecessary upvote on the same content multiple times

3. The same countermeasure as number two —metadata following every stake to track who gets what from who, then lock it up from performing the same thing

Some users are recycling content. Why is this? This is basically a symptom of an underlying system condition and users are accustomed to this subconscious awareness of how useless their posts will become in a matter of a week
