You don't even need a mirror website, hiding flagged posts is a setting.
Is it a setting that requires a certain amount of karma to display?
I don't think so. It's called "showdead," right under email on the settings page.
Thank you. I've seen the option. Didn't know it was the 'flagged' display.
I would call the tone of 4chan (insulting everything and anyone) to be gatekeeping, specifically against those who wish to have more moderation/"nicer" discourse.
IMO gatekeeping (by the community) is a good/necessary thing for spaces to not become completely gutted/become kicked out of what was formerly your space.
I think this image sums it up quite well. https://img.ifunny.co/images/8f4199becd35483d8f498f9ccd0eb73...
Dang regularly asks people not to make throwaway accounts routinely and bans people that do. See https://news.ycombinator.com/item?id=34142620 for one example.
Not arguing that, but generating smurfs on HN is pretty trivial compared to a few social media platforms I can think of. Luckily there isn't much money to be made from doing it here, unless you want to play the long game and try and push an investment agenda, but again, that isn't really hot-take territory and more like creating many false identities over a long time.
Still, HN could make a couple of changes to email verification and make smurfing much less trivial. I think it is good they don't
For everything else there is documentation, experimentation, social clubs and entertainment.
1. There is a 'account system' for reputation, but it is trivial to auto generate throwaway accounts for 'hot takes' or counter group-think. There are even simple mirror websites that allow for browsing without hiding flagged posts. No Edit:[I don't think any] attempts have been made to reign this behavior in, likely for good reason. Perhaps it keeps the discourse interesting and encourages lateral thinking?
