Poll: Were you banned by AdSense? When in the cycle were you notified?
I use AdMob for a mobile game I made. After successfully using it for years I got a notice that Google had bought the company and that my account would now be an AdSense account. I started earning money there and when I reached the 100usd amount, with no explanation at all I got banned. I filled up contact forms but not reason was given to me. They just said that I was not going to have my money since it was going to be refunded to advertisers.
After a while, for some strange reason my account was luckily reverted to a classic AdMob account and now I'm back again getting my money through PayPal.
I'm really disappointed on Google support on this matter, there are no email addresses or real people to talk to. Amazon and even DX have given me better customer support for 2usd items.
