This submission was made by a 5-year HN user with 14000 karma. Although I don't know if you've been more active with a different handle, which is certainly very possible, the account whose submission you're complaining about has been active 27 times as long as yours and has 91 times as much karma as yours... suggesting a history of reasonably good-faith contribution to HN.
Edit: it's true that his submissions aren't primarily about IT topics, but people continue to find them interesting.
