Instead of banning and charging,HN could double down on trust signal,like device reputation,posting velocity limits,and stronger weighting of upvotes from long standing accounts.
I analyzed multiple months of submissions for rule breaking / political content and the vast, vast, majority of them came from the same ten or so 50-200k upvotes power user accounts. The most "trusted" accounts on this site are the worst offenders.
But if you say anything against it, you get downvoted and dang reminds you to read the guidelines which are intentionally vague and are misused all the time for vendettas. It’s a rigged system to start with.
There are some users that 100% are protected by mods.
Users will get threatened and scolded for getting mildly confrontational on a tech topic, but plenty of user can flamebait endlessly in political threads unimpeded.
