It's probably an iOS app client for HN. CFNetwork is like their URLConnection I think. You're blocking people who want to read your article!

As for why it occurs so often in quick succession, perhaps there's a bug in the app causing it to fetch several times instead of once.

Thanks, I thought it was a bug in some app and just wanted to be sure, so I don't have to babysit the server.

If anybody knows which app is that, please tell the maintainer that they have a serious bug. It's night here, so I am logging off.
