I have been on HN ~5yrs and only like last week I started getting an auto-ban of sorts about "you are posting too fast" even when I post ~15min+ between posts and then it takes something like 6-24 hours (haven't kept trying to measure it) to reset. Been meaning to do ask hn post about this but that counts against my daily allowance of like two posts (hope this one makes it lol). I think moderation (in general not at HN specifically) should be transparent, truthful and measured. But at the same time, if you don't pay to use a site you have no say in how it is operated. I would like to know if I said things that are not welcome at hn? Or perhaps I broke rules without knowing it? I try my best to be reapectful and kind to others but I also do get angry at some posts and let emotion get the best of me sometimes. But if I did something unacceptable I cannot stop doing it unless I am told what that thing is, so shadowbans work against the moderator's interests if the moderated subject is being cooperative. At HN: the decision to allow political and controversial non-technical posts also means accepting undesirable or controversial views (even if they get downvotes) else you are just creating an echo chamber of ideas. I had a post where every hour or so when I checked it goes upvote then down vote all day long because it was controversial I guess but I thought I simply had a strong opinion on a subject instead of being hostile or posting something irrelevant or invaluable to the discussion when I started noticing the restriction. But like I said, I have no qualms on any moderation decisions on a free to access site. But also, I am very supportive of solutions to scale moderation. I really think paid human moderators can be scaled for many online communities and social networks. Why isn't FB hiring people for $12+/hr to moderate stuff? The idea that it is either humans or ML as opposed to humans working with ML is silly. Or maybe they are already doing that at major social networks. I always wondered why reddit for example doesn't allow subreddit members to have paid subscriptions to support moderators.
