I feel like in this day and age it shouldn't be that difficult or expensive to have a bot that would notify curators when posts where the main attraction/value is meant to be photography/artwork/etc that gets recycled to alert us in the comment section.
This would help stakeholders/curators to avoid each individual to have to google reverse search every time and if it's just a banner/other usecase where it is re-used but the focus of the post is the content/other then curators could just ignore the comment.
But yeah, authors definitely shouldn't be recycling content knowing how the reward mechanism on hive works, there were some artists a few years ago who made a big fuss out of this but needless to be said you can't compare our reward pool reward mechanism with ad revenue or other things people may be used to.
We should adopt a "common list" among the most active curator communities, with x people behind it, the same as the curation teams or community owners, to ensure that everything is independent.
It could be a step forward towards more careful (but not more stringent) control and above all that the abuse is seen and supervised by everyone. More than anything that everyone is notified at the same time.
