I'd say calling out some random yelp dev for bad yelp reviews is even more shady. Why don't you tell use your real name and what company you work for now?
Bringing in someone's personal details to use against them as ammunition in an argument may or may not be 'doxxing' but it's a shockingly bad thing to do on HN, clearly a violation of the guidelines and a bannable offence. We won't ban you this time, but please don't do it again.
