I think downvotes will help in regulating in terms of quality post but it also gets abused sometimes.
I feel there should be a body that will be allowed to doenvote instead of every user. A body that will prevent abuse of hive power.
A lot of downvote battles have been going on already on hive
But then, that body would be centralized. Centralized parties follow agendas, and agendas have proven to, most of the times, follow the interest of the few against the interest of the many.
How could we regulate such a centralized body?
Well, i feel there should be a criteria and then something like May be different witnesses or different users who will agree for the post to be downvoted.
This is just a suggestion
