If you are asking about moderator decisions the place to ask is info@ycombinator.com - it's gotten quick and intelligent replies to me when I asked.
I suspect that it has something to do with a very busy time for YC and the landing page you linked to looks like a bad Spanish SME selling something to clueless small businesses - I had to scroll all the way down to find you are actually open source and on GitHub
I am not saying you are the above - just your website does not sell you very well. I would look at Drupal.org for inspiration perhaps - emphasise community and open source - and really really really dump the semi-porn surprised looking woman and laptop. 99dollars on 99 designs will do far far more - or just ask on HN lots of good designers around who may be willing to help
