So the article, while peer reviewed, clearly shows an agenda and disinformation. Which means the publishers of the journal have an agenda.
These are the exact same reasons why I caution against believing everything in the PPH just because it's written by a doctor. He doesn't provide evidential support for his claims or his rationale for peacefulness and reliability ratings. He runs businesses: a book, seminars, Max Dog. He ain't no tireless, selfless saint.
It's like being hit from both sides. No one in a position of power is genuinely on our sides.
And fear of SN becoming unavailable just makes it more desirable and appear more reliable, much as the accessibility of the PPH is limited.
On the forum, some folks have genuine concerns and fears about the method, and in response, some defend it more emotionally than factually, cherry picking the evidence and sources to support their defense. I get so tired of battling against it, it just keeps going. Others spread fear, like the repeating trend @SpottedPanda is picking up on -- they're not always people saying, "Hey, something's off," but a concerted effort from multiple directions to heighten fear, which means folks are more easy to manipulate in that state. I strongly suggest you recognize when you're in that state and step back from what's happening until you can get back to a state of being able to think critically.
How then to manage all this?
Take responsibility for your own death, your own wants, and your own goals. If you don't have the skills to read and understand how to accomplish the method, how to determine the potential symptoms and risks, and make an analysis about the reliability of information presented, either don't do the method, or take the risk at your own reward or peril. If something smells off, respect that. It's your instincts protecting you. The smell of bullshit means bullshit, and while it may fertilize flowers, they are just a diversion, the bullshit wasn't spread for them. Don't let your desires overwhelm your safety when your gut says you feel unsafe.
If you feel helpless about this, simply don't do the method. If you don't feel confident and in control of your ctb, you're more likely to fail or, in the case of this method, have to recover with outside intervention, which, based on your personal situation, could fuck up your life even worse. If you also feel helpless because you don't know what else to do, I get that. So many are in the same situation. All I can say is do your best to not let it push you into what your gut says is not safe or you're not sufficiently prepared to do. Find a cope. Keep researching reliable methods that are simpler. Desensitize yourself to them, like leaving out a rope and getting use to seeing it, play with making knots, watch videos. This is not encouragement to ctb, but empowerment to to be able to do as you choose. Who knows, you could overcome the fear of a method and realize there are a lot of other fears that you would be capable of overcoming and no longer seek to end your life because of them if fear is what motivates your voice to suicide.
TL;DR
If you need a TL;DR version of this comment, seriously, compassionately, I don't think it's wise for you to mess with SN. It's more complicated than reading and comprehending this post. There are a lot of variables to consider. I suggest instead that you try to read my last paragraph above this one, that starts, "If you feel helpless about this." Take your time with it. Ask me to clarify/simplify if there's something unclear about it. I'm happy to do so.
