Overview in Help Center Explains GBP Suspensions

Google has now made it very clear that any content added to their Business Profile must accurately represent the location in question and follow the policies and guidelines. This support link gives users their best look yet at what they should and should not do to their business profiles, along with the consequences that may come with violating these guidelines. Violations can lead to the removal of content and potential suspension of your Google Business Profile.

Google regularly updates policies and guidelines, publishing articles to summarize the thought process. Violations result in restrictions to access the profile or merchant account. If an account is disabled, suspended, or deleted (in other words, "not in good standing"), a merchant must take steps before they're able to access their Google Business Profile.
