I mean the word 'boring' in the HN sense of not intellectually interesting. Something can still be exciting even if it's boring in this way. It's boring because there are only so many ways to denounce something as "the epitome of toxicity", "this person made me cringe", and so on, which means the patterns of denunciation get recycled a lot. That makes them predictable, and this site exists for things that aren't predictable.

Another way of putting it is that indignation tends to melt down to a few formulations that get repeated a lot, where intellectual curiosity looks for what is new and different in a situation, and then has a new and different reaction to that.

Since we want HN to be a site for intellectual curiosity, it's important not to feed indignation too much. It quickly overwhelms curiosity if allowed to (especially on the internet); therefore we need to moderate it. You're right that the moderation comments are boring; that's because they're also predictable. If it helps at all, they're even more tedious to write than they are to read.

For what it's worth, I think it's ok for those comments to be boring.

The root comment has been hidden, and the mod (who probably hid it) has replied to it stating why it was hidden.

That we can see moderation is a good thing; that moderation is 'boring' is to be expected.
