Well I only see a few cases, so don't get the full picture. I know it's hard work that may not get appreciated. If Hive grows rapidly then it will get worse.
We often get discussions about downvotes and I still see them as an essential part of Hive. Having them decentralised is important.
I am still trying to understand myself. I have seen more cases than I would like. I've been reading a lot of the downvoted posts to try and understand the problem because they do a lot of good work and so do others. I want systems put in place that can minimize the attacks on the ones doing the downvoting that protects the HIVE blockchain and prevent misunderstanding from happening because of the downvoting. The more resources for and people doing the downvoting the better off we will be. Because as it stand now there is not enough communication between downvoter and the one downvoted for multiple reasons. And I think a comment system that a downvoter could partially automate would help.
