#1 Question: how would this help steemit/steem grow?
Wouldn't more downvoting cause more drama and conflict on the platform making people want to leave or not join?
The majority of downvoting I've seen are bigger accounts downvoting smaller ones. That's why I see downvoting as more of a bullying tactic than what it was actually designed for with making sure whales can't rape the reward pool.
I think you should focus more on protecting the reward pool from rapes rather handing out free downvotes or WMDs as I would call them to everyone on the platform.
