I pay for app engine, if I want human interaction then I have to pay an additional $150 a month. Google does this for services it charges for, so it is hardly surprising that it does it for ones where it is paying money.
Its not about human interaction, its about citing clear reasons and giving chance of proving innocence before suspending anyone's account and taking their money. Its impossible for a computer to understand arguments made by publisher and that's why there is need of human interaction without having to pay for it.
