How many people downvote content they agree with or find funny but doesn’t add to the discussion?
Again, this is only a problem because we have lost this sense of shared culture. If we really want to have an established "community", these guidelines will have to be one way or another be restored and enforced.
How many more complaints about downvote bullying are mods going to have to field?
Here is an idea: instead of trying to remove power from people, let's give more of it. Hiding votes is hard, but creating a finer-grained permission system for moderation is not. Let's build a system where mods can assign other mods for specific types of reports. Then, we can have few mods who would be "all powerful" like they are now and we could have a bunch of "issue-specific" trusted users who could access/triage specific reports.
We shouldn't need mods to figure out what is "basic" spam and we shouldn't need powerful mods to say "user A is reporting that B has downvoted their last 5 posts in different conversations. This is a violation of the community rules and therefore should be banned."
This feels a bit of a conversation-shutting argument. Lots of things (good and bad) will happen on a platform that has billions of users. The real question is to about many of those instances happened solely due to the data being (easily) available to the public.
In any case, I really don't think that the solution to the problem of targeted harassment is by providing quote-unquote-privacy. Today, people want to obfuscate votes. Tomorrow it will be subscription lists and later it will be even posts/comments. By then it will be better to just use a closed network or just go full darknet. I'd rather we spent more time educating the people on how to use actually secure and private communications platform instead of sacrificing Transparency and Accountability for the sake of a vocal minority who will keep trying to turn the "Open Social Web" (which is meant to be open and public) into their exclusive, cocooned service.
