When running ads without advertising on Google, your account may be banned immediately or for a long period, depending on the severity of the violation and Google's policies. Usually, when detecting fraudulent behavior or policy violations, Google will suspend or ban the advertising account immediately. Account bans can last from a few days to several weeks, or in severe cases, the account may be permanently banned. To avoid serious consequences, you should comply with Google Ads regulations and advertise transparently and legally.
