That said, two things:
You should send a message to hn@ycombinator.com if you have something to say to moderation. They're very responsive, and you'll get a better response rate than posting in random HN threads that might not even be seen. It also breaks the Guidelines:
Please don't post on HN to ask or tell us something. Send it to hn@ycombinator.com.

You also shouldn't take this personally. The poster likely didn't see your post, very likely wasn't 'gaming' anything (they actually have some really interesting articles in their submission history that don't seem to have been posted before, and they're a journalist; it was likely they just read it and posted it), and it wouldn't be practical to 'ban reposts': HN already has a feature that upvotes a previous submission if you post within a given range from it.
I know it's not a great feeling to post something that you think is interesting and to see it get to the front page later via someone else (I can point to a bunch of my own posts where this happened), but it getting to the front page at all is something positive. It's not a race, so incentivizing quick-draw on articles from popular outlets (like zdnet, which has millions of readers) above all else probably wouldn't be useful, either.
