It’s growing everywhere. The problem is subjective, which is why the current model fails. I’ve tried to suggest ones in the past where users have more control about general moderation in their communities or can at least choose their curators, with communities themselves are more decentralized from their instances, but there is no interest, at least not in losing that power of control.

The people who downvote after every reply don’t really help, they either just want the last word or aren’t really interested in an honest conversation. The anonymous downvotes don’t really help either (specially when they coincide with thread upvotes coming from accounts with no comment or post history that just seem interested in nudging the conversation to an alt).
