I've said this elsewhere, but I rather suspect that downvoting stuff doesn't decrease its visibility much. I haven't actually applied a regression to the data (though now that I think of it, that'd be an interesting problem), but eyeballing vote totals on my replies heavily downvoted vs. comparably upvoted posts at the same level of the comment tree, I don't see much difference. That implies that about as many readers are expanding the tree as would follow it normally.
It seems obvious to me that, at least in theory, stuff can get upvoted that we don't want here, for reasonable values of "we don't want". Do you disagree with this? (And in practice, I think this particular post is an instance of such stuff.)
Not in principle, but the main class of stuff that would get upvoted but which the community wouldn't reflectively want around is stuff that exploits some kind of short-term bias. Flattery, tribal politics, that sort of thing. I don't see a good case for putting this post into that category.
A flat up/down voting system is insensitive to degrees of dislike, too, and if the response to a post is highly uneven -- lots of lukewarm positive responses and a few very extreme negative ones, say -- then dropping it might be good for the forum despite positive karma. There might be a stronger case for saying this is such a post (though they should generally be rare), but on the other hand this line of reasoning leads to some nasty strategic effects downstream; I think we ought to be extremely cautious about using it as justification for removal.

Huh? Once the post drops below -4 net, it becomes really hard to see it and costly (5 karma) to reply to it. There is a clear threshold effect.
My stupid fanfic chapter was banned without explanation so I reposted it; somehow it was at +7 when it was deleted and I think silently deleting upvoted posts is a disservice to LessWrong. I requested that a justification be given in the comments if it were to be deleted again, so LessWrong readers could consider whether or not that justification is aligned with what they want from LessWrong. Also I would like to make clear that this fanfic is primarily a medium for explaining some ideas that people on LessWrong often ask me about; that it is also a lighthearted critique of Yudkowskyanism is secondary, and if need be I will change the premise so that the medium doesn't drown out the message. But really, I wouldn't think a lighthearted parody of a lighthearted parody would cause such offense.
The original post has been unbanned and can be found here, so I've edited this post to just be about the banning.
