• "Sorry I don't speak Mandarin." --- They cannot scam you.
• Don't allow phone banking or digital banking. --- They cannot scam you. This is what they rely on for transfer of funds to them by victim.
• If you are a male, don't allow female strangers to "friend" you on Facebook. 99% they are in a Myanmar scammer prison camp and forced to try to scam you. They are NOT who they claim to be.
Scammers know how to get to know you and over a period of months, psycho you to "invest" or transfer funds.
