A sudden ads suspension arrived, with no explanation beyond "suspicious payments". This from the same billing account used with GSuite, Domains, GCP; and from a business that was having no trouble running ads on FB, Twitter, and Reddit. "How silly, but I'm sure we can get it fixed".. I thought.
Like OP I'm also a Xoogler, so after two rounds of unsuccessful appeals through the front door (including updating my payment account to a hard card, providing articles of incorporation, and so on, to no avail), I figured it was time to call in my first ever favor. Surely one of my old-timer engineer buddies could thunk a ticket somewhere and maybe we'd help them fix a bug in some automated system in the process.
But the Google of 2022 is far different than the earlier days. It seems individual employees, even well-placed engineers, have incredibly and increasingly limited agency to fix things outside their immediate purview; a wiki about internal escalations for ads suspension stated they were no longer accepted, vaguely for reasons of "compliance".
On the bright side, the whole episode made me rethink and ultimately diversify our technology dependency on Google. I was naive not to do so more seriously and earlier.
