Several Google AdWords advertisers posted complaints in the Google AdWords Help forum that their ads are being labelled as either gambling related or pharmaceutical, resulting in either special certificates required, delays in ad approvals or disapprovals of ads.
Laura from Google confirmed there is a bug with the Google AdWords automated ad approval system. She said:
This morning we found a bug in the approval systems that was incorrectly flagging some ads as gambling- or pharmaceutical-related when they shouldn't have been. We're in the process of sending all those back through our systems and re-reviewing them from scratch so the problems get fixed. There's no ETA yet, but I hope it will be soon.I apologize for the mix-up.
So if you have this issue, I assume you just need to wait for Google to fix it.
How long? There is no ETA.
