How is hellbanning supposed to be better than, say, a mod telling someone off or banning them and giving a reason for the ban? Assuming hellbanned users are actual spammers, they're still generating spam. Assuming they're not, legitimate and potentially interesting content is being stifled.
Killfiles probably wouldn't solve that specific problem But I think they might be more equitable. Maybe if users could spend karma to upvote them out of a hellban?
I feel like I'm a responsible user and someone just didn't like one lighthearted comment I made. It's pretty upsetting actually. It's a shame but, I guess I'll just not post anymore. Will anyone even see this comment?
