I got my "Final Warning" from Adwords a few days ago, although I never knew I was doing anything wrong. It was just one page that I set up and forgot about which received a low quality score -- and when I asked them to see a list of the "multiple violations" that they repeatedly mentioned, they replied that this single occurrence was the only one.
Seeing that it is this easy to get banned, and I am very interested in Adwords promotion, I am wondering what I can do if I get slapped dead.
At the very least I could pay a consultant to run my own campaigns for me, couldn't I? But managing others' campaigns would be out of the question?
