It's a very tricky subject. I'm sure you're right too. I suspect there will be a handful of people who pull this kind of stunt for attention or to try and dissuade people from using a method.
Still, it can also work in the opposite way. Imagine a genuine member genuinely attempting and it's not working out. I suspect they're terrified and they can't talk to anyone else, so they come here for support and get the third degree in questioning, plus people calling them out to be fake. I do remember this happening once... I think the consensus ended up being that they had been sent something other than SN but, it can't have felt great for the OP:
last night i attempted: 1 hour before - paracetamol 45 mins before - domperidone 3 x 10g and propranolol 30 min before - 3 valiums took a couple mg melatonin and smoked some weed about 5/10 mins before SN drink - 20gm in 50ml water i'm so confused, i woke up this morning a bit drowsy but...

People can get extrememely defensive of SN in particular I've noticed. I can sort of understand it. It's my likely method too. It's unpleasant to think it could go wrong. Really, it would be better to actually know of failed attempts if we could be sure they were genuine. Including- why they likely failed. That's surely how protocols are formed- people collating data to see what the most successful attempts entailed. But, I don't know how we could differentiate genuine attempts from possibly fake threads.
I think there needs to be a balance between people genuinely trying to find out why an attempt may have failed- which I guess includes wondering whether it is a genuine post. Still- I don't think we can do that openly on a thread without insulting the OP- who could be genuine.
