"I discovered this neat new hack called 'fraud'"
Why fraud? If we are talking about criminal law, the requirements to convict a person are strict. In this case the author has not claimed neither on Patreon or YouTube to be someone he is not. He has not falsified any data/documents and has not stolen any account, since the one he claimed was available.
Sketchy? No doubts. Fraud? Doesn't seem like it at all.
