I like it that Kaj took action on this issue. The trouble was that there was nothing obvious for me to do that didn't require programmer actions; I didn't know how to reverse Nier's downvotes or prevent him from downvoting further. I have not been putting heavy attention into moderating LW and I don't personally know how to use the more complicated moderation tools.
I do however know how to click "Ban" when Will Newsome tests the limits of LW's tolerance for crap, and it's upvoted to 7 points and I don't trust that Newsome isn't using sockpuppets to upvote.
This is somewhat tangential, but neatly links the two recent dramas: I was actually one of the first people subjected to campaigns of mass downvoting, having had hundreds of my comments downvoted in bunches on multiple occasions. Although there are exceptions, from what I've seen the well-intentioned extremists who unscrupulously abuse the karma system have generally done so in defense of your well-kept garden.
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.
