> negative feedback - and dismissive feedback - is something you need to be prepared
OK. Let's RFM: first line = "Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes."
So, no, it's not HN-OK for rude & unfounded feedback to make it to the top comment.
Even if the website is "bad" (i.e. those 30 papers were never linked to Ilya etc.), the proper way of handling this is to call it out in a neutral way.
