This is still the same kind of fraud as the earlier one you mentioned, nothing has changed. It involves making friends on the internet and chatting them with ulterior motive. This kind of friendship is risky because as days progress, the innocent and gullible person starts developing feelings for real friendship and can fall for anything the other wicked person says.
But on the other hand, apart from friendship scam, the real reason people will be scammed is because of greed. A greedy person might want to outsmart the other person and maybe get hook first, or , a greedy person does not see something wrong in abnormalities and so would not see the trap just layer in between kilometres while they keep stretching to get something kept in miles and thereby, falls on the ditch...
. More like a rat trying hard to get some fish while the trap is just before where the fish is.
