My site was just launched last month, didn't get $100 yet. Today I found a message in my Adsense account, saying "Your payments are currently on hold. Action is required to release payment." Is this a warning message?
It usually means that you need to provide additional info (maybe tax related, maybe address, whatever.) It doesn't mean you've been banned. Take a close look at your account info. Cheers, JL
It said a PIN had been mailed to me. So seems I have to wait for about 2 weeks to get the PIN from the postcard.
