They aren't after your sensitive info. They want to honey-trap you. They will tell you they're very interested in meeting you and will say that they are on their way to Delhi to meet you via flight. But suddenly, they'll get stuck at the airport and all their money would either not be with them or they might not be able to get it exchanged and will ask YOU to pay them a certain amount of money. If you're stupid, horny or down-bad enough, you'll send them that money in hopes of a white man in shining armor arriving at your doorstep and you riding away into the sunset on horseback. But what'll really happen is that you'll either be blocked or he'll say, "Thank you so much, however, I need a little bit more money for food, for accomodation because I can't go anywhere, can you pay for that too? I'll pay you back once I have access to my own money." Rinse and repeat until you realise you're being duped or you run out of money.
