Correction: it's the 4th(!) post of this: also https://news.ycombinator.com/item?id=42757076 and https://news.ycombinator.com/item?id=42753842
I've been curious about this author's stuff trending on HN despite being of average quality at best and seriously problematic at worst, now I'm suspicious if there's some kind of reputation farming being attempted here.
What exactly is your objection?
I've had to manually click backwards through my own comments, but the comments on this https://news.ycombinator.com/item?id=35271498 are a good illustration.
And that is the 3rd or 4th time posts on this domain have triggered some warning flags for me; if you can tell me how to search my own comments on HN by post domain I can give you more links (not going to do more manual backwards-paging…)
As for searching, if you scroll down to the bottom of the page there's a search box, you can add your username to the query and it'll match.
That gives me the few submissions I've made, but not my comments, and not specifically my comments on posts from the domain nullprogram.com :/
… but it's probably time to leave this be, too.
