As was pointed out by Dan at 3speak in our recent community chat, it isn't really possible for the community to rally to counter downvotes as long as the downvotes aren't easily visible. That is part of why I am going to make that possible soon and he has stated he has funds set aside just to counter the downvotes.
As far as people shitting on Hive goes - I only know of a small number and they aren't really on Hive any more.
Well I read it with my own eyes, probably someone you're defending while grouping me in with people who overdownvote in your post.
It doesn't sound like rocketscience to build a tool that notifies people when big downvotes occur late while filtering out hivewatchers or anti-abuse accounts like that so many can go and decide for themselves if they want to collectively counter said downvote and share the loss of ROI from that vote with each other until it's back to a realistic/fair reward.
