Hi! I'm the creator of Leap. Glad to answer questions here.

Why exclusive to Facebook users?

Perhaps because Facebook provides an easy and fairly reliable way to determine someone's sex. Many projects including dating sites have relied on it to do authentication for this reason.

I fail to see how it'd be good for this use - do they require a number of friends or something? I have 4 Facebook accounts for faking out exactly this kind of stuff, but none with any real information.

Presumably most people are not like you and have only one account. The site can make sure you have had an account for at least a year and your sex is female. Otherwise you may want to fake it to get in.

It's the most reliable "easy" way I know to determine this info. I remember an app called Lulu which did the same.
