A couple of weeks ago I received a notice that Google was suspending my account because my ads violated AwWords' "mirror" policy. This is a policy prohibiting landing pages that are mirrors of other pages on the internet.
I checked all of my pages, which are hand-written originals, and looked on the internet for copies. I found nothing, and emailed AdWords support. They checked, found nothing, and un-suspended my account.
Today I received a notice that my account was suspended because it violated Google's "counterfeit goods" policy. I don't sell anything counterfeit, and told Adwords support. They checked, and lifted the suspension.
Is anyone else having problems with out of the blue suspension?
Unfortunately that is how they work. They are quick to suspend accounts, sometimes with and in your case sometimes without apparent reason. I think its at least partially due to how they manage that part of their employees/department. One reviewer will say a page is ok and another will suspend an entire account for something on that same page that the first reviewer approved
You were lucky that they gave you the info and were able to get your account back online.
