This is a dangerous scam by African scammers who are out to cheat unsuspecting women (and sometimes men) from all over the world out of their money.
They go and create fake profiles on the internet with stolen photos and made up names.
Then they write to women and try to get in touch with them virtually. If they succeed, they quickly play the women the big love.
At some point the question of money comes up. They always need financial support and the woman should pay.
So if a stranger sends a friend request or wants to get in contact with you, be careful until you have seen the person in real life. Anyone you only write with is a potential scammer. Only in the moment you see the person face to face in person (not on video) do you know that the person exists.
never send money to strangers
