It's not to deny that these things are a problem, just that it can't be fairly decided here.
There might be vindictive posts but people could judge them on the merits of their argument and history. But you are going out of your way to prevent expression. What is there to gain?
Should users reply somewhere else or email HN directly? Should users accumulate karma and downvote or flag the posts? Care to put this in the text on top?
Suppression is actively affecting people, though I'm not sure how harmful it is yet. There's already self-moderation happening (community votes), so again what is there to gain?
