It is impossible nowadays to become a new member in Reddit

I mean I work as a Marketing Manager for a website and we actually have more than 60 great authors. Our articles are so different and true that Microsoft wanted to be our partner this week. But I don't know why people won't click on my submitted links when I know they are really good.<p>And now, Reddit won't even let me submit any links saying: "you are submitting too much ...... another 1 hour..." and yet I can't submit anything anymore!!!!<p>Please help me to understand the new way new members can get Karma!
