Visible post and comment scores are still going to produce some of this behavior. You may not have a total karma but people will still get dopamine from seeing their posts getting upvotes and be reinforced in doing the same again. So the same mechanisms of social pressure and uniformisation are at play. The worst being when people delete their minority opinion comments because of the downvote pressure.
This kind of indirect bullying is kind of unavoidable online, because of the lack of direct contact, you don’t empathize much with the other sensitive being. Until we get that perfect education to civility that may happen in 2000 years if we still exist. Maybe one solution is to have strong rules and moderation about personal attacks. But then it’s the moderators that will get bullied for censorship and end up crucified on the power tripping bastard community.
