Yes, I agree with you, but it would be wrong to call scammers stupid these days because scammers these days are so talented that you will always be defeated by their talent. They trap you in such a way that there is no way to understand it. Now it is not the old days when we can say that scammers are stupid. Their tricks are now very dangerous which we do not understand, so we should be careful. Do you think scammers of today are stupid?
Scammers are indeed stupid, because if they were smart, they wouldn't have to scam for a living. They are just unencumbered by a sense of morality, which enables them to do things that an average, decent person wouldn't do. There's nothing "smart" about that. I've dedicated a lot of hours here to defeating their talent and have been often successful. It appears you're on the other side. May the best man win.
scammers are often pretty stupid
