The number one goal of the steem blockchain should be attracting more eyes on the page. Downvoting does not do that. When the downvoting pool gets misused and it will be, you will have people chased off the platform.
The value of a post is subjective and sometimes people are jerks. Downvoting empowers jerks and puts us all at risk. There is no appeal process offered. Instead, empower those people that encourage engagement and a growing community. Change policy so that it is more difficult to scam the system and/or create a block-chained backed downvote curator to deal with the bad hats. Downvote wars are not in the best interest of the steem blockchain. Infighting is not attractive.
