Introducing a classical judicial system would only create pandemonium. I think once we have 1account=1stake voting we'll be able to recreate the way we vote for or against others, in a fairly accountable way. This is the type of voting I was hoping for in the beginning of Steemit as I was looking for a solution to vote manipulation in classic polling methods.
Back to the point, I think we'll be able to squash platform degraders once vote changes are implemented in the future. At least that's where my understanding is of future changes, I could be wrong. Either way we're moving in the right direction; forward!
