Do you really want law enforcement wasting time and resources (read, taxpayer money) on these pathetic civil fraud schemes? I'm sorry, there's much bigger fish to fry.
Life requires a certain amount of personal responsibility. If one is too ignorant to not fall for a completely unrealistic scam (hmm, somebody wants to pay me 4x my ask price for my plane>?????!!!), it's not the duty of society to protect them.
