The only time I ever got an email from a real human at google was when I tried out google cloud for a weekend when it first came out. I had a detailed plan to benchmark different instance types and compare them to AWS for an upcoming project.
I got about two hours into this and my account was deactivated, one of the cloud engineers sent me a truly nasty email saying that bitcoin mining is not allowed on google cloud and I should stop abusing resources and being so irresponsible. I replied and asked how on earth they came to the conclusion I was a bitcoin miner and explained what I was actually doing, but never heard back from them again.
It was so bizarre, I felt like I was back in the 3rd grade getting in trouble for knowing more about the Apples than the computer teacher.
