Ask HN: is content from my URL auto-killed?

I'm a publisher of a European news site for startups & innovation. As such, I submitted about 10 of our 100+ stories to HN in 3 weeks, every time taking care that they were 'interesting to hackers' (ie they were about startups, VC, accelerators and such). If I read the HN rules correctly, I didn't break any rules.

All of my most recent stories were killed, one an interview with Adeo Ressi of Founder Institute (original content, an interview I did myself), another a story about a 60 yo startup founder (original content, interview I did myself). Today, a spotted post about font sizing and design for iPad mini.

Would really love to discuss this with a HN editor.
