When I first signed up for Adsense I had real feedback in two days, human response, very kind. Since then... only automated emails (if any) and standard answers quoting things I can find on their documents online... so nothing new.
Google's biggest mistake in my opinion is that they made the adsense program way too accessible. I'm sure we've all seen the teen trying to get clicks by obsessively demanding his visitor to 'click here!'. Or the unknowing naive guy trying to make a buck by giving people some form of credit for clicking adsense.
I totally agree. They must be too busy dealing with "I was banned but I swear it wasn't me, please please please forgive me"
