apologies if this is a dumb question, but what does 'hellbanned' mean? i understand folks' concern about dubious intentions, but if it's any consolation, this is merely a class project from Clay Shirky's Designing Conversational Spaces class at NYU.
Hellbanned means the poster sees his own comments as normal, but no one else can see them. Someone who is hellbanned typically does not know they are banned until someone tells them (or they eventually get suspicious of no one commenting on their comments or up/downvoting). Frankly I find the idea of hellbanning childish, but it has a long history on the internet.
But if you hellban them, then they'll log in just fine, they'll post just fine... but no one will respond to their posts. Eventually they'll get bored because they can't get a rise out of anyone and they'll leave.
