A friend of mine was originally from Nigeria, which she put on Facebook and was grouped into the Lagos network, as that was where she was born. Within a week she'd had literally hundreds of friend requests & messages from guys in Lagos telling her she was the most beautiful woman ever, that they want to marry her, etc. It's been about two years now and literally not one day goes by that she won't get a new message off some guy looking to score. It's almost terrifying the lengths some guys will go to when they want to get laid, even if the girl's on a different continent.
I changed my network to Lagos, and in case you were wondering, no, you don't get inundated with requests from hot Nigerian women.
