I'm confused. Comments have up/down voting, and posts have up voting and flagging.
> In a democratic system like Reddit, there might be objections to changing the titles or shadowbanning trolls (reddit does shadowban, but mods can't shadowban people for disturbing the quality of a subreddit). On Hacker News, these features are welcomed because they raise the quality of discourse.
I've seen both people posting "you're hellbanned and it doesn't look warranted" and productive, moderator-accepted complaints about changing titles.
