I was rejected again and again and again. First few times I was rejected as I didn't have an at least 6 month old account. As soon as my account was 6 month matured I applied again unpublishing 30 hubs as I had a lot of hubs written on sensitive issues and ads were disabled in those. After one month they reviewed my application and rejected again. I applied with my blog then and got rejected again. I applied again few hours ago with all my unpublished hubs republished all and adding 4 more with those and you know they have accepted me now. I think it was all about time as I did change nothing.
I will write a hub about my long journey of getting adsense. Many substantial Asian and African writers become highly discouraged being rejected again and again. Unfortunately the are the victim of Google's security system against mass spamming by the majority of the users from the stated regions. I will try to keep them motivated and encourage to keep writing. Hard work and patience really pay off.
Congrats Shifa on getting adsense. I knew it was just a matter of time before getting approval from adsense as you are a good hubber. I am so happy for you. I can understand your excitement and remember the day I got my adsense approval almost a year ago.
