Having an account (or a curation trail) curating good content, helping new and old underrated users, but with a strong eye on how much one extracts from Hive could be somewhat of a start
Indeed, that is also what I have been thinking. A curation group that sets some ground rules when it comes to value extraction, and even leaves comments on good content form users who are a net negative on Hive that they would have gotten an upvote if it wasn't for their value extracting behavior.
I'm also sure a lot of the HP delegations would flow out to this and I would not mind delegating some myself. I have thought about starting something like that myself but I don't have the time and tecnical skills. It would be nice to have a curation mechanism where users can summon a vote (like the old 'minnowsupport' system) like once or twice a week with clear rules in terms of the content and the overall contributution. Or something like the old busy.org upvotes wich took in consideration the amount of followers you have an their total stake on the platform.
Yeah, it would be cool and maybe it could make more people aware of the importance of curating authors that not only post good content, but also are invested into Hive - or at least aren't extracting everything they earn.
In the past I wrote some scripts that, with some little work, might get the job done... but I feel that a project like that needs someone well known by the community to get some traction and have an impact on the chain.
Agreed: this would also make the project easier to manage, because the whitelisted users would act as curators and find themselves the posts that deserve an upvote. The project would only need to check if the post fit the requirements for an upvote and, if yes, calculate the percentage of the upvote according to its own criteria.
