From December 2020 Some Advertisers’ Accounts May Be Paused Until Business Operations Verification Is Completed
https://support.google.comIn December 2020, Google will be updating the Business Operations Verification program requirements to reflect that certain advertisers’ (applicable to advertisers in Australia, Canada, India, Ireland, Pakistan, South Africa, the UK, and the USA) accounts may be paused until the verification is completed successfully.
They may pause advertiser accounts immediately and require them to complete Business Operations Verification if they find that their business model is unclear and they suspect that their advertising or business practices may cause physical or monetary harm to users.
Accounts will remain paused until the verification form is completed, reviewed by Google, and deemed to meet the requirements of the verification program. Once those criteria are met, any ads that are policy compliant will be able to serve.
