To Viliam,
Trolling/flaming/spamming report buttons are clearly labeled for their purpose. The downvote button isn't.
To Nornagest,
Here's the big difference: On Facebook, you can't stop OTHER people from seeing what the person has to say, no matter how much you scream at them. With the system here, you can. Their posts will be hidden and they can even lose their posting privileges when they are downvoted. And when I say that's a big difference, I mean that's a BIG difference. Again, think of the religious forum. This same karma system would allow them to literally stop you from speaking to or influencing people who are on the fence or more open to rationality, instead of just posting replies that highlight their own immaturity or irrationality. I think the issue here is clear.
Secondly, when you refer to (I presume) LessWrong as "an ideologically-mixed environment that values things other than conformity," you're assuming that everyone here views it that way. If everyone saw the downvote button in the same idealized form, we wouldn't have a problem. The issue is that the downvote button does not have such a clear and apparent definition, and there doesn't appear to be any actual enforced policy by the LessWrong admins to stop people from using the downvote button to simply express disagreement.

Can't you? Eliezer cites the easiness of clicking a button and making the other person Go Away as a major perceived advantage of posting on FB rather than LW. And even if you downvote someone on LW, well, someone can undo that with an upvote.
Last month I saw this post: http://lesswrong.com/lw/kbc/meta_the_decline_of_discussion_now_with_charts/ addressing whether the discussion on LessWrong was in decline. As a relatively new user who had only just started to post comments, my reaction was: “I hope that LessWrong isn’t in decline, because the sequences are amazing, and I really like this community. I should try to write a couple articles myself and post them! Maybe I could do an analysis/summary of certain sequences posts, and discuss how they had helped me to change my mind”. I started working on writing an article.
Then I logged into LessWrong and saw that my Karma value was roughly half of what it had been the day before. Previously I hadn’t really cared much about Karma, aside from whatever micro-utilons of happiness it provided to see that the number slowly grew because people generally liked my comments. Or at least, I thought I didn’t really care, until my lizard brain reflexes reacted to what it perceived as an assault on my person.
Had I posted something terrible and unpopular that had been massively downvoted during the several days since my previous login? No, in fact my ‘past 30 days’ Karma was still positive. Rather, it appeared that everything I had ever posted to LessWrong now had a -1 on it instead of a 0. Of course, my loss probably pales in comparison to that of other, more prolific posters who I have seen report this behavior.
So what controversial subject must I have commented on in order to trigger this assault? Well, let’s see, in the past week I had asked if anyone had any opinions of good software engineer interview questions I could ask a candidate. I posted in http://lesswrong.com/lw/kex/happiness_and_children/ that I was happy to not have children, and finally, here in what appears to me to be by far the most promising candidate:http://lesswrong.com/r/discussion/lw/keu/separating_the_roles_of_theory_and_direct/ I replied to a comment about global warming data, stating that I routinely saw headlines about data supporting global warming.
Here is our scenario: A new user is attempting to participate on a message board that values empiricism and rationality, posted that evidence supports that climate change is real. (Wow, really rocking the boat here!) Then, apparently in an effort to ‘win’ this discussion by silencing opposition, someone went and downvoted every comment this user had ever made on the site. Apparently they would like to see LessWrong be a bastion of empiricism and rationality and [i]climate change denial[/i] instead? And the way to achieve this is not to have a fair and rational discussion of the existing empirical data, but rather to simply Karmassassinate anyone who would oppose them?
Here is my hypothesis: The continuing problem of karma downvote stalkers is contributing to the decline of discussion on the site. I definitely feel much less motivated to try and contribute anything now, and I have been told by multiple other people at LessWrong meetings things such as “I used to post a lot on LessWrong, but then I posted X, and got mass downvoted, so now I only comment on Yvain’s blog”. These anecdotes are, of course, only very weak evidence to support my claim. I wish I could provide more, but I will have to defer to any readers who can supply more.
Perhaps this post will simply trigger more retribution, or maybe it will trigger an outswelling of support, or perhaps just be dismissed by people saying I should’ve posted it to the weekly discussion thread instead. Whatever the outcome, rather than meekly leaving LessWrong and letting my 'stalker' win, I decided to open a discussion about the issue. Thank you!
