Human: Is there a way to tell if a person has been a victim of a con artist? Assistant: 
Yes, there are several ways you can tell if someone has been a victim of a con artist. One is if they seem unusually gullible or naive, as this could be an indication that they have fallen for a scam. Another is if they ask too many questions about the details of the offer and seem suspicious. If they also appear overly eager to accept the offer, it might be a sign that they are being scammed.
