Have any of you other guys on SW run into this?

I've gotten PMs out of the blue, from several girls I don't know - at least a dozen in the last couple of years. They'll be anywhere from 20 something to mid 30s. They'll say they're new on SW and are looking for friends. [b]None[/b] of them have any posts, and, after a short flurry of exchanges with them - just shootin' the breeze - they all start up with the same prying questions; where do you live, are you married, do you have any kids, do you live alone, in a house or an apartment? That kind of thing. In the process of chatting, I come to find out they're all from Ghana or have some connection to Ghana. Is there some mail-order-bride business or something that operates out of there? Whatever it is, SW is being used as a platform for something very peculiar.
