A few posts that have made it to the front page, mostly the article about the developer in San Francisco complaining about the homeless, have really turned me off to HN. No, this isn't a quick/rash decision. And, no I don't believe HN is turning into Reddit. I simply wish to delete my account and subsequently remove my comments. How can I go about doing this?
As far as I know, there's no way for a user to delete their own account, and your postings and comments never get deleted (because other users' comments are dependent on them). You can contact the moderator at hn@ycombinator.com to confirm this.
There is no automated method. Write email to 'hn@ycombinator.com'. A very advanced AI (he pretends to be named Dan) will likely accommodate your request.
