All Simon Whistlers YouTube channels contain plagiarism and rehashed videos from forgotten/unfound channels and he gives no credit. Just watch his latest video on his newest channel about Tarrare, then go watch the same video on the Sam O'Nella Academy's channel it's a damn near 1:1 telling of the same story.
