Google are very picky about what content they allow their ads to be displayed on. They banned one of my websites (thankfully not my whole account) because of a few rude jokes. So if your videos or pictures are sexually related in any way, there is no way they will allow it. They will also not allow Google AdSense on any websites that portray violence such as weapons.

If you want to work with Adsense, you should have AT LEAST 10 good articles in your blog in a GOOD niche! Then, do NOT use any other programs like Adsense and don't forget that you should NOT request an approval more than once!
