I have posted all thing cr@king and premium apps for free. But I never used keyword like h@cking, cr@acking on my website. And also my website was 20 days old when I got approved in adsense.
So the main thing is that, for adsense you have to make quality of content.
each post must be 300 words minimum and at least 2 images. choose proper keyword.
do not use keyword like h@cking, cr@acking.
