I was replying to your assertion that ‘Flame wars, abuse etc. only happen if there are other people watching’. DMs are an example of a major abuse vector where other people are not watching.
I understand. However, on my platform, there is no even username so it is very hard to follow people around. Also there is one reply per node limit and per user comment limit per day to cap the volume.
Anyone must be able to take a small amount of abuse to survive this world. I can't eliminate abuse but I can increase the friction of abuse and make abuse less satisfying or rewarding. That's all I want to do.
Also anyone get only one chance to reply, unless the reply is approved.
