Yeah, I made the mistake of connecting my blog and YouTube to AdSense too early. Google decided that there was "abuse" going on and banned me.
They ban you FOR LIFE. They refuse to tell you why or give you any specifics. AdSense is crap! I tried many many times to get hold of a PERSON who could explain to me why I was banned. Nobody ever contacted me.
My wife created an account and we tried that. However, since she's connected to me, they banned her, too! WTF GOOGLE?!?!?!??!??!??
They claimed that by telling me how the ads were being abused, they would reveal information that could allow people to circumvent their testing process.
They never even warned me. Never did I receive an email saying "hey, we see something screwy here."
Google is the Gestapo!
