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.

And a few other times over the past week:

It doesn't matter how much karma someone has. A repost is a repost, and it's ok to point it out.

I took this as somehow blaming GQ itself. (I don't mind people pointing out reposts.)

It matters to me. The reasons the parent outlined are roughly the factors used for my personal trust rating when considering if I mind veering off topic momentarily while reading.
