I posted an item on Facebook Marketplace, and a person contacted me asking if I had a Carousell account and if they could purchase it there. I agreed and sent them the Carousell listing. Then, they messaged me on Facebook again, saying I could scan a QR code branded with Carousell logos and pages designed to mimic the official site. Upon scanning, it prompts for credit card details. Realising it was a scam, I hope to inform the wider public about such scams. Please stay alert!
