I downvoted you because you asked people to explain why they were downvoting you. This adds nothing to the conversation (everyone who gets downvoted wants to know why, everyone who downvotes knows that the person who they are downvoting would want to know why) and is bad for HN (talking about the moderation system distracts from actual on-topic conversation, and leads to gaming of the moderation system - indeed, I would say even that line can be gaming the moderation system, as it can lead people to reconsider whether to downvote).
