I am not banned from Adsense and they have not paid me for over 6 months despite the owed amount is a bit more of $200 USD.
They said it was a problem with the new interface back on September 2011, later due to technical problems affecting a few accounts, later because my account had to be synced, afterwards for unknown reason and the last I heard from there about a month and a half was that they were "investigating" why my payment is not being issued yet despite the account is actually working.
Of course I stopped to run their ads since it smell to scam, and therefore the finalized earnings have not increased through this time.
However, by the end of May when "this time you will be paid" last email arrived, they stopped all communication and began to send auto-responses saying that "nobody" attends such email when I was in contact with them through this address all the time.
If this is not scam, I don't know how can we name it. In fact Google is acting like scammers do, avoiding to provide reliable contact methods and shutting down the available.
