SCAMMER: “I am real. You must know that Facebook marketplace is full of fraudsters these days. No one can be trusted these days. I think you are not a fraudster. Still I want to check with you. Hope you don’t mind. Ok I want to send a 6 digits number via text. If the post is real, show me then I’ll call you. Can I send it?” (Replied about a marketplace ad)
( The scammer had called and will return calls with texts. So you can leave a voicemail or text and say your returning their call about their interest in a sofa, a refrigerator, a washer, a dryer etc. any one thing.)
