You seem to be the closest person on this thread who can answer questions about Google. Can you please tell us why Google summarily suspends accounts? Why is there absolutely no way to talk to a human being?
I can't speak for Google, and I don't work in that part of ads, but my understanding is it's primarily because of how adversarial fraud detection is. If you give people who violate policy detailed information about what they did wrong and how you know then it is much easier for them to figure out how to abuse the system without getting caught. I don't like it, but I also don't know how to fix it.
Let me rephrase this to make it clearer what the actual issue is: it's primarily because the cost to Google of false negatives on fraud detection (failing to detect actual frauds) is much higher than the cost to Google of false positives on fraud detection (flagging users as fraudulent that actually aren't). So Google is willing to accept a large number of false positives in order to avoid false negatives.
Or, to put it more simply: the incentive structure of what Google has chosen as its core business model means it is in Google's interest to randomly penalize a large number of bona fide users simply because a much smaller number of users are fraudulent.
In other words, this is basically unfixable unless Google changes its core business model.
See the problem?
