It comes with the free market and free-willed, self regulated community.
Think about it. Normalize downvotes

If and when Steem fixes the downvote system, then, maybe then I will do some down voting. Until then the Idea of Normalizing a broken system is unacceptable to me.

Know that in a self regulated community, there are highly influential people that can and will use their stake to do what they think is positive for the platform

If this is true then perhaps you can explain the continuing case of new 25 REP accounts that receive 15 SP delegated from Steem and have done nothing but troll and down vote people. These are not accounts of people that are Community Members. They do not participate in the Community, they do not comment, they do not post, they do not give upvotes, they only down vote, these accounts are well known, and very little of the delegated steem has been pulled from these accounts, and when it is pulled then another one pops up and continues the down vote marauding.

Normalizing a bad behavior is wrong. A blanket no explanation down vote is bad behavior and should not be nor be expected to be normalized. If a person feels strongly enough to down vote a post then they should be required to leave a comment with the down vote, even if it is an automated pre-formatted comment.

Fixing the down vote system would not be hard, but until that is done then you are advocating the normalization of Bad behavior. That is just my opinion.
