A post only needs a score of -1 to be hidden.
By default, posts with -2 or less are hidden. (I just created a new account to check). I'm pretty sure the default used to be -4.
The post currently stands at -12 points, in addition to ongoing punitive serial-downvoting of his (and my) further posts on the issue (most of which both did not mention the spoiler and were hidden under the hidden post).
That is not relevant to anything I said. People can downvote for whatever reason they want, and should generally do so to mean "I want to see fewer comments like this one".
By default, comments with a score of -2 are visible and with a score of -3 are hidden. The preferences page is confusing because it uses "below" as a strict inequality. I believe this was the original default, though there may have been something else in the middle.
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
