Facebook only was stupid to start with, but 100+ facebook friends requirement is something else, it means the service is only open to a specific kind of profile, the one who add people without thinking. Funny thing is in my online dating profile, I have a requirement similar to yours: that people getting in touch with me have no facebook account.
