Ran into that too! We were spending about a million dollars a year on AdWords. Part of Google's requirements are that we give clients access to the Ad accounts as well. One client did not have Google accounts, so we registered some for them, granted them access, and provided them to them. Of the dozen or so accounts we set up for that client (it was a group of car dealerships under one high-level umbrella, so separate but together), one got suspended almost immediately by the accounts team. We submitted a ticket with the accounts team regarding it, and when it was still banned a few months later I finally reached out to our contact at AdWords. She submitted a follow-up ticket with the accounts team. By the time I left that job about 4 years later, she still had not received a response.
