Us "haters" are just tired of seeing people fall for the same scam over and over.
I completely understand your point and I actually appreciate your input in this community, where - as in many emerging ecosystems - a lot of unthrustworthy individuals try to make an easy profit by abusing people.
So let me thank you for this, as I haven't done so.
My point was that by saying things like "yet another scam you fell into although we had told you !" you kind of push people to defend themselves "no ! it's not a scam ! time will prove me right".
And then when your interlocutor realizes it's a scam, he stays silent to avoid mockery.
That's exactly the opposite of the purpose you're looking for : you want to prevent anyone from being scammed, and for that to happen you have to encourage people to come to public forums like this one and describe their problems. It's the only way to "break the cycle" if you see what I mean.
The "sorry for your easily avoidable loss" wasn't meant as a "told you so", but as a reminder to anyone reading this to do their due diligence. Just about every scam in bitcoinland in the past few years could have been easily avoided if investors had done minimal due diligence.
I agree that the more people admitting they've been scammed, the less people will fall for that particular scam. Though at that point it's really too late because it's normally after the scam collapsed. The amount of people admitting they've been scammed has little/no effect on other scams and proof of that is the fact that there are already a hundred+ threads full of scam victims yet people either don't see them or ignore them.
IMO what we need is for people to keep pointing out what should be obvious, i.e. do due diligence, stop paying for unbacked promises, demand more proof than renders, etc. Once that becomes common knowledge then these scams will never take off to begin with.
