However, we are careful to intervene less in controversial stories about YC or YC startups. That's the first thing PG told me about moderation and the thing he has emphasized most. So I'm going to suspend the usual rules and leave this one untouched for now. If it falls in rank, it will be purely because of user flags, and if that changes for any reason, I'll edit this comment.

Edit 2: Enough users have been flagging this post to auto-kill it. I've unkilled it four times so far and will try to keep doing so, though I can't promise how quickly. (Flagging rarely kills a post—usually it at most lowers its rank—but in cases where flags overwhelm upvotes, it can.)
