I fail to see how this is a personal attack. I was basically saying I don’t understand why people always have to post these ostensibly on-topic, actually off-topic humble brags (?). Where’s the attack? “You know perfectly well”? People have really thin skins these days if that counts as an attack. I see multiple more aggressive comments in this very comment tree (e.g. “it's an ignorant and arrogant take”) and IMO even those hardly crossed the line.

"You know perfectly well" is already edgy, but when you follow it with "I don't understand the motivation of these $dumb-comment-paraphrase" and then a "like, come on" and a "you're not impressing anyone", you've crossed well into personal attack.

You're a great HN user and commenter and your contributions are much appreciated! I don't want to come across like a bag of bricks but if you would use this feedback to fine-tune a bit, that would be appreciated.

(You may be right that other commenters were breaking the guidelines worse, but we just don't come close to seeing everything, and a lot of what we do see happens by random access.)
