So many people have succeeded with SN after all, so I believe it to be a reliable method. But still, it's unfair and disrespectful for people to call those who failed SN and posted about it, to be deliberately creating doubts about the method in a suspicious way. The reality is that ctb methods can potentially go wrong if not researched properly, so all that anyone can really do, is do their research on their method to prevent this.
It's horrifying the thought of ctb potentially going wrong, but as I said so many have succeeded. There is a reason why so many go for SN over other methods, I mean it doesn't sound as peaceful as N but still sounds preferable to many of the alternative ways to ctb, at least to me.
