If you are getting scammed into a transaction (by providing you fake or consciously misleading information, misleading possibilities of monetary gains, etc.) - is that really a "voluntary" transaction?

I think "voluntary" should mean that both parties know what this transaction would realistically mean for both of them and the actual risks involved. When you are being scammed (by many of the ICOs (not all of them)) - that does not sound like a voluntary transaction to me.
