Given Tor and VPN, and the fact that both are fully acceptable to connect to HN - as far as I know - this would add nothing of substance.

The reason why it works on Elon's kingdom is that - as far as I know - the Onion services died when Elon took over (because the people who cared about those simply left) and over at X - as far as I understand - they really, really try and discourage you from connecting and posting from Tor and VPN.

Also, when people turn discussions into absolute flame wars or decide to post stuff which could turn nasty in the comment section there's always dang. And believe me when I say that even when community moderation fails for whatever reason the rules (https://news.ycombinator.com/newsguidelines.html) will get enforced when needed.
