the problem is that you have also lazy curation on Hive. Those who read that see the problem. You as a Hive stakeholder should be concern if the rewards are going for people who abuse the system. We are all responsible to get these... If you just care about your rewards and Hive stake you can see the blockchain going towards the mud.
On top of that downvote is there as part of your free will the same that upvote. If you don't like my comment for example you can just downvote it is your choice!
