After a whole day search, FINALLY I found a way to contact adsense directly for my questions. I'm very happy to share this link with you. However you must refer to the Google Adsense Forum for your answers first. If you don't find any help then you may email google adsense directly. The link is given below. Hope it will help you. I suggest you must bookmark this page for future reference: CLICK HERE to contact google adsense. Keep in mind that, due to huge amount of emails, Google Adsense will take sometime to reply to your queries. Please let me know if you have any suggestions.
No you can only ask adsense related questions from Google Adsense from above link. But u should make sure to find answers in their Google adsense forum before. However you can appeal for a disabled account by CLICKING HERE
My answer is yes. But first you have to look for ur answer in Google Adsense Forum. If you can't find an answer then u can ask Google Support directly and in these cases they'll surely reply u.
Not yet, but they'll surely reply to me cos Google Adsense Forum didn't gave the required answer. I've also posted the question here in digitalpoint. You can check here
I think you should contact a Google forum senior because they can contact Google employees and so your message goes to Google quickly. But I am sure the other way you are following would work as well
