I swear many years ago you could delete old posts but not any longer. About all you can do now is do something so egregious that they delete your account.
There's likely many iterations of HN comment datasets out there from "show hn: I scraped everyone's comments for my comp sci/big data class" over the years.
That’s actually how I got my Facebook deleted in 2015, and it appears I am still banned. I posted a picture, from behind, of a cowboy wearing only chaps. I tried to join again around 2022 to sell some stuff and they rejected me.
Probably the best move I made for my mental health tbh.
Have they stated the justification for this anywhere? You'd think a site that brands itself as being for hackers would value its users having control over their comments/privacy.
There's value in editing for clarity within a window of a live discussion. After the live discussion is less active, it's important to be able to reference things or see a coherent view of the discussion and what people were responding to.
Yes, it's because the comments create a discussion thread that then becomes impossible to follow (or worse, misleading) if certain comments within it are either deleted or edited to say something different. The idea is that what you write becomes communal property once it's been responded to, because it's part of a community discussion that loses meaning if people start deleting individual comments.
Pretty sure they only change the username to something anonymous though, and remove any PII in comments you've written, right? They won't delete the comments themselves AFAIK.
