I never got around to posting this when it happened, but about 2 months ago, 2 of my websites and several clients had their adwords accounts shut down on the basis of suspicious clicks. One of the sites was new and had only accumulated 14 dollars in revenue in a little less than a year. Did anyone else have this problem and if so how did they fix it? Thanks!!
Email customer support or call them and get them to investigate. Usually some automated system shuts people down, then they can go in manually and reinstate things.
