I was rejected but explained the nature of my site a bit more on their help forum and surprisingly that's all it took. i know it's impossible to find someone to e-mail and you think "oh great, a forum", but they do look at that. So make your case!
To get adsense approval you need good and fresh content and one domain which is 6 months old will be excepted by Google instantly hope you will get adsense approval by this way i have one more idea but i cant tell you ....
no budd, i disagree with almost everyone in here. you do not necessarily need a year-old domain to register. my original account has already been banned for "fraudulent activity", but from my experienced. 1. you need a professional design. 2. a good amount of visitors...10k/day? 3. good non-illegal website...and legitimate unique content. good luck mate.
