Still a tiered support system: last year I started a side project and I wanted to advertise on Google. Created the AdWords account, with all the legal documentation and everything, it got banned in two days. All the support I could reach was bots. Luckily I had some friends at Google who could escalate internally....
I bet they still have a level system for the advertiser support, there’s no way an actual developer reads the first message. Maybe for very large customers they have a dedicated support line, but not for a small business advertising on google.
