I suspect you and I are talking about two different things however.
I'm using fraud as an ordinary layman would use it - that is - deliberate deception to secure unfair or unlawful gain.
In this case, I think most people would agree that spawning up multiple dummy accounts (e.g. john001@gmail.com, john002@gmail.com, john003@gmail.com) and then using them to get around ordering restrictions is definitely deceptive. (These account names are obviously illustrative).
And in terms of what's a "reasonable" response, that's above my paygrade. All I can comment on is the public statements that those people made around the time, and around their interactions with Google and their interpretation of them.
However, are you a legal practitioner? If so, then perhaps you are using the term in the other sense? Also, if you're willing to comment IAAL, that would be very interesting.
