Here’s couple of hints, previously their story is that they’re Malaysian workers in China or Singapore etc. Nowadays they use Malaysia phone numbers, even have instagram account with stole pictures. The chat are pretty decent, sharing stories etc. within a week, they will tell you about those money games or investment or trading they been up to and earned decent amount of money. That’s a red flag, when you questioning them about it they’ll just spin around or accuse you being sensitive. Saying “You changed so fast, i don’t know what’s wrong with sharing experiences about making money.” etc.

Long story short, don’t get too attached first on those matches. Once they start talking about money or investment or trading, you can block them because they only want to scam you.
