I would like to point out that in my experience the hn admins respond much faster and friendlier than I had ever expected. I think in this case it is very nice thar "just email the admins" leads to experience like that, although I have no idea how they manage that for a site at this scale.
Being inconvenient can be a dark pattern on its own, not necessarily needs them to ignore your request.
Like, if I email them and say "hey, I want to remove these 340 comments I made out of 2000", and I do it every other day, would they still be as responsive? Even if they do, collecting and emailing all these links is still a big hassle compared to just clicking "delete" as I go through my own timeline like other social media platforms.
