Do you really think that this is an analogous situation? As in, that Graham's advice, if followed, will predictably and directly lead to serious physical harm?
To answer your question literally, no, it's not exactly the same. If it was, I'd be recommending a few folks be banned.
To answer the question I think you were really asking, yes, it's analogous. And if you don't agree, I'm prepared to argue you are not studying budo but some odd, stylized exercise regimen.
