The problem with that is the author's unawareness of risk aware kink.

If someone is doing breath play, or applying blood restriction during their play, they know damn good and well it's never fully safe.

The problem comes in with noobs and idiots thinking that you can bypass serious effort at learning how to minimize risk with reading some random internet article on a bot written blog.

There are absolutely ways to make the risk so minimum that it has to be some kind of unknown factor driving the risk upwards and not being accounted for to cause injury or death. But those things do happen. It's a real and unavoidable possibility.

There's also difference between strangulation and proper breath play, but that's another example of a writer not doing due diligence in terminology
