Why?

I received an email from google ad sense today telling my application had been denied due to the issue of unacceptable site content. I wonder what are these contents that hindered their approval of my site. As far as I know, I haven't written or done anything against their policies. Maybe my site is too young for them or maybe I haven't meet their standards of writing or unknowingly, maybe I have done or written something that is unacceptable to them. Well,there is nothing I can do about it so I removed all the ad sense and continue posting in this blog. After all I am having fun doing this. This serves as my daily diary and an outlet of bursting the emotions I have kept. So, no matter how much I wanted to be given an approval by google ad sense, I must accept their decision and still continue blogging. Hope I will last longer as a blogger.
