There are clear and common ethical standards here and the blog post comes in well under them.
No, the context is now reframed as a post on a highly-influential site, this one. The author is now commenting here, which is great.
But "Don't try something like this without at least talking to a doctor, I probably should have" has yet to appear on the post. Therefore I reserve the right to state my objection.
And a disclaimer to make sure that the person reading the comment is competent to assess whether their doctor is competent?
And a disclaimer that there may be errors in the disclaimers, so think for yourself a little bit?
Personally, I'll take an article like this one where the author doesn't much represent any of it as advice over an article that claims to give a bunch of advice but qualifies it with a disclaimer that it might not apply, check with an expert.
