I don't really think that the community should be stunting it's own distribution of rewards in order to prevent some people who are obviously acting in bad faith from disrupting everything. On the other hand, if that's what the community wants then it should be tried! I suspect you will just see people pumping out a high volume of posts with a low reward limit, however. "Here's my 30 part recipe for boiled eggs".
I think you should start making extremely badly written and short recipe posts and earn 150 USD. Looks to be a lot easier than trying to think!
I think that pretty much nobody wants to limit their earnings on a post, and that is drawing a lot of the fire from the Downvoters. There also are no clear standards on why a post about a Photo Challenge post is OK to make 50 USD when it only took a few minutes to do, but a post you do that might have taken you an hour to write and hours of research is bad at 50 USD.
There seems to largely be no rhyme or reason when looking at the Trending Page getting upvotes VS the people getting downvotes.
There's definitely scope for making the rewards algorithm more intelligent, but a lot of the best ideas rely on oracle data that is either hard to reliably obtain or that can be gamed. For example, if there was a way to accurately measure post views and inbound traffic from posts then it could be directly integrated into the rewards.
Unfortunately, to be decentralised and open source this would require a lot of code and processing that is kind of off-topic for Hive's tech as it stands and the data could possibly be gamed too.
A system that is based on subjective valuation of stakeholders will always be inherently warped towards the opinions of the biggest stakeholders, it's not only a route for 'winning influence' with people but also even money laundering too. Just as NFT sales seem to often be a way of laundering money, I can see how Hive's reward pool could be too.
Solutions need to take all of this into consideration. I think layer 2 communities are probably the best bet but they need to be very configurable and available without investing $1000s.
