But even if you did disclose, it's still against HN rules, as other people in that thread told you. You commented "they’re free to delete it. I think it adds value", but as you've seen the community disagrees.
Not according to the guidelines and the upvotes the comment received.
The search thread you were linked to (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...) are comments from dang, the head moderator of HN. His word is the law.
Well now that sounds dystopian.
If you think about a behavior, and wonder if it is within community norms, not behaving that way is the simplest thing that might work.
Or you can always ask the moderators using the |contact| link at the bottom of every page.
And sure you can just do it and find out what happens. If you do that you have no reasonable complaint and “sorry” is the best response.
And for better or worse, lawyering the guidelines is not in the spirit of HN. Better because moderation is generally patient, kind, and soft touch. Worse because the guidelines are guidelines not so much bright lines and some people want bright lines.
