How to tell if a buyer is scamming you on Facebook marketplace?
There are certain red flags such as new accounts, only a few friends, or friends who are all foreign (weird names), or their photos look stolen (like they have a foreign name but photos look American, or going through their profile pictures, they are different). Then if I know they are a scammer, I report and block. Things you should never say to scammers, never tell a scammers that you are on to them and that you love them, please do not wear your heart on your sleeves or say anything about your research effort and finding. Sometimes they work in a group using the same profile picture and portfolio.
