alt Hacker Newswhy can't we simply raise the bar for posting? I remember semi-open platforms, where you were invited, had to earn the right to post comments and posts. and you could easily lose those rights when downvoted. its seems strange in the AI-bot era that we allow any entity the freedom of speech.
That's essentially how most small chatrooms work these days. Join a bigger GC or small Discord/Matrix/IRC and bad behavior gets flagged with impunity. But most of the big web forums like HN, Reddit, etc predate that and moving to a model like that would pretty much kill the sites as we know them.
